Saw this posted on another board (PM me of you want to know...) and sharing here due to the obvious relevance.

The POST (sic):  
Another close call on SA.
.
It's a cold day in your typical midwest college town. I had arranged a noon meet with a new 21 year old at the hotel bar. Her SA account was only a week or so newly created. Looks were good on the site, and she showed up on time AND looking a little BETTER than her pictures.
.
She guzzled 3 mixed drinks while I sipped a couple beers.... as i had an afternoon meeting later. She then suggests we head to my room at the hotel.  
.
After a bit of small talk, I learn she used to be a dancer. I did NOT recognize her, but i dont get to this town often. Once she tells me her dancer name i immediately remember. While shes gained 10 or 15 pounds since I'd seen her last about 1.5 or 2 years ago, she was still looking fine.  
.
Arriving at the room, I notice its snowing. Hard. Didnt think much of it.
.
We had an enjoyable time and I was satisfied. She quickly gets herself put back together and says she had to get going, hoping to see me again soon.
.
Didn't think much of it until an hour later. She texts me a picture of her totalled car. Thank God shes not injured, nor cited for DWI.
.
Thoughts running through my head...... should have sent her home in an Uber. If she was hurt... am I somehow liable for buying her the drinks? Was she really 21?  
.
All is well that ends well, I guess. Close call.

There were several replies with mixed perspectives, though the overriding theme was: not his problem.  I disagree.

Here is the reply I posted:

My REPLY:
Hmm... excellent topic for discussion. I see several angles that bear exploration here:  
.
1. Ethics:  From an ethical POV, I think you had an obligation to help her get safely home (or wherever). Not because she's an SB, but because you have a moral obligation to anyone who might be impaired and you see they probably should not be driving. The situation would be the same if this was a "regular" date, a friend at a party, or a work colleague at a "business lunch."  She may not have accepted your Uber or other offer, but I think you erred in not connecting the dots between 3 drinks and bad weather.  
.
2. Legal - From your POV: I don't think you are on the hook for the type of liability (medical, car repairs, property damage, time lost from work, etc.) that may come from a lawsuit or criminal investigation.  She's 21, was there on her own volition, ordered the drinks herself, did not commit any crimes (except DUI), and you did not coerce her in any way. But...
.
3. Legal from her POV:  If I was her lawyer (I am not a lawyer) and she asked  me to sue you, I'd go to town on you full throttle. I'd suggest you coerced her into prostitution (you didn't), you deliberately pumped her full of  booze (you did not), you threw her out of the room when you were finished "using" her (you did not) and you did it all with negligent indifference to her needs or incapacitated condition (again, you did not).  These arguments would probably, ultimately fail as the actual laws are on your side. But you might have to see all this play out in court in front of a jury and perhaps in the local press. And, if the lawyer finds out you were at the hotel as part of your regular work hours or work assignment, he'd likely sue your employer for negligence for not properly supervising you. So you would have to fully disclose your Sugaring to your boss and company, risking your job, professional reputation, and possibly retirement benefits.  
.
So ultimately, I don't think the important question is "Am I liable?"  The important question is "Do I want to go through the process of proving I am not liable?"
.
You might want to follow  up with her and see if she's ok, needs help with car repairs (even if it means giving her a few hundies) and generally express your concern for her and willingness to help her "get back on her feet" (pun not intended, though it's a pretty funny pun).  And from a Sugaring POV, that's the right thing to do as well, assuming you'd like the option of seeing her again the next time you are around her area.

Note: If the OP was one of you, feel free to jump in or stay the fuck out of this, and accept my apologies if I overstepped posting here. But I do think this type of issue does not get discussed her as often as it should be.  
.
So to the rest of you:  What is a SD's responsibility and liability wrt the safety of a SB post-meet?  
.
For me....

If she didn't get a dwi she probably wasn't that tanked, which can be used in your own defense (she didn't appear drunk.)

Now if she did get a dwi and if she really looked obviously drunk, that's when you'd have a possible reason to worry.  Not necessarily because of what you did, but what she might claim you did ... pour drinks down her naive throat, etc.

I don't really know any big drinkers, especially SB's as big drinkers ... but I do tend to watch for guests at parties who might be a bit under the influence when they're leaving.  It's never really been an issue.  But I think I'd catch it if I was sending an inebriated SB home -- and make sure she was ok or until she insisted on leaving.

Thanks for your reply. Just to be clear, this is not my story. I was presenting a post from another board made by some SD in the Midwest who had this experience.  When I've seen my SB drink heavily, I always get her safe transport home, even if that means driving her in her car and taking an Uber back to my home.

Because I had a similar situation a couple years ago.  I was dating a really lovely 22yo SB who insisted on beginning each of our dates with a bottle of wine.  I'm not much of a drinker so she wound up consuming most of it and became more relaxed and more amorous as the date progressed.  I was concerned about her consumption, but clearly not as concerned as I should have been.  She wrecked her car on the way home from one of our dates, injured her elbow, got a DWI, and I felt responsible.  Turns out she had  had a few drinks before she showed up for our date that day. I helped her as much as I could. Shortly after that she ghosted on me.  The lesson I learned from that is I simply DO NOT include alcohol in my dating any longer if there's any chance the girl is going to drive home.  Right now I'm dating one SB who has said she'd enjoy relaxing with a few drinks before the fun starts.  She usually drives to my place and then drives home, but I'm not going to give her alcohol and then send her on her way.  I'm trying to arrange picking her up next time, so she can enjoy some adult beverages before our adult activities, then driving her home or ubering her home.  But if she's driving we're not going to have any alcohol.

Wise words.  
.
Between the two parties to an arrangement, it is we (the 40-70-ish SD guys) who have a real appreciation of the risks associated with booze (or whatever) and cars.  Although there is something to be said for finding an SB that get's more amorous with booze, it's up to us to ensure we make that happen in a way that keeps her safe (and able to come back many times to fuck our brains out).

I like to include drinks as a component of BCD activity.  As a matter of fact, one of my filters on SA excludes "non-drinkers".  Typically, will share a bottle of wine.  Occasionally that is preceded by dinner in which we'll have a drink as well.  

On one occasion, I had a young SB who was not a wine drinker and requested that I bring bourbon and Coke.  She was so nervous on our first time BCD, that she had about 3 drinks before the activity.  Afterwards, she was completely out and clearly unable to drive.  As it was a late afternoon rendezvous and I had to get home, I let her sleep it off.  Checked the room in the AM and she was gone.  Met a few more times and on each occasion, I let her sleep off the buzz.
