She needs another 30 minutes.  
At what point do I leave?

your thoughts if any?

Sets on . Look for the dude leaving ? Ask for a mini review .

.. your thoughts if any.  Fucking annoying. Also, leave immediately.

The answer is easy..  
Don't leave.  
Leaving, then coming back looks suspicious..
Just go through your car.. Organize things like you would if you were going to spend a night in a hotel.
You just didn't have time to put everything together.... Look for things that aren't there.. Check for dents on your car...
It really works.

It's easy...
Just look busy.

END OF MESSAGE

Was 30 mins.  That was 2 yrs ago. I was at the bar. At the appt. hour she called & said she was stuck at the mall shopping & was waiting for a taxi. 5 mins turned to 15 to 30.  She arrived as i headed to the car.
I should have left, not worth the wait.

On a better note:
More fun was when the booker told me head up.
Knocked on the door. No answer for 2 mins...that feels long in a hotel hallway.
She came to the door & said just a minute.
She opened the door in a hoodie sweatshirt, let me in, rushed to the bathroom.
"Sorry, gotta put my face on..."  
She offered refreshments & I watched a porn star get pretty.
When she was ready...25 mins later: Wholly Moses!
She just stepped out of Brazzers...
She gave me extra time & then some!

Look for dents ? Where on your head ! Leave means leave . She could have texted him .

It has happened to me multiple times on early dates.
Looking busy works.. Bugging out like you are a drug dealer doesn't.

If I've seen her before and I like her I may cut her some slack.  If it's a new girl I may not.  If I give her the 30 minutes and pass the guy before me in the hallway I'm not even bothering to go in...

I'd decide if I was going to be available in 30 or what ever (frankly, it makes it much more difficult to do the disappearing act from where ever I was supposed to be).  I often arrive a bit early since weather & traffic can cause delays & cause well planned meeting to fall apart.  What I do is locate the call point & then withdraw to the corner coffee shop be that on premises or off.  I time how long it takes to return...  typically 2-3 minutes.  I will often call from the coffee lot, in my car...  I've had gals watch me pull up & all was fine.  
Personally, I think more that 15 is disrespectful of OUR time unless she has an apology & a good reason.  I'd take it on a case by case basis...  
Hotel Security & patrolling LE watches hotel parking & loitering is a good way to get the attention of those people.  Sitting in a car reading the newspaper outside a hotel...  just before the hour...  is a red flag for vice officers.

I saw Jesus

WTF is up with hooktards today? How can anyone get a real job if they can't even be ready on time to suck a d(ck and not even have to DRIVE to do it?

Hey...it's possible  

I had 1 told me she was bathing . She passed me on the street . Then kicked another out of the apt. That 1 cursing up a storm ! Still with me . Then I go in after I get a call and she Like well she just ran in .then I get a bottle of water and she tells me she likes daTy ? Then I left . True fucking story . Then she calks me and asks be to write a review ? I said of what ? Nothing happened ? The rest a soap opera . I hate NY . Glad its a temporary stop at times.

LMFAO

Or, writing her thesis on how sperm makes you stupid bwahahaha.

It depends.

At one time medical professionals asserted that ADHD only occurred in children, AND that they outgrew it.  IE, did not exist in adults.

It was only after getting in touch with a woman I dated in college, way back last century, during the mythical times of the late 60s, early 70s, that I heard of ADHD in adults.

Seems as if someone questioned the mythology and discovered many adults had ADHD.

When she described her symptoms, I heard much of my life story, except I do not have the hyper activity.  Turns out the hyper activity does not rule out a brain being structured for ADD.

I get board easily, easily distracted, UNLESS I find something fascinating; then I am super focused, my surroundings disappear, I loose track of time.  Even when I pay attention to the time, I always think I can just finish what I’m doing and leave on time.  But, I loose track of time—run late a lot when I'm doing something interesting.

Another symptom is that I forget where I'm headed. When I ride down a road I normally travel, I keep going that way, past where I should turn.  Instant lateness.

When I worked, I had a routine of getting up at the same time, leaving at the same time, drive the same route—rarely late.  Yup, I'm retired now.

I've always been independent, many years on my own.  I can keep myself entertained, find something to do; I usually bring a magazine to appointments so that I have something to read, something interesting to do.  Clean my motorcycle while waiting; I live on a dirt road so it's always dusty.

Plus, I don't ware a watch any more—clocks in every room of my house, even bathrooms and on my motorcycle.  The result is I never know how late my Dr was for my appointment (unless it's a practice that does not take any insurance, Dr are ALWAYS late!)

The last three years of my wife's life we were constantly going to Dr appointments.  She lived in constant pain—pain Dr two medications, GP for referrals and regular appointments—three medications, Dr to take care of depression because of constant pain and life on pain meds Medical testing and then another Dr because of kidney failure with following 3 appointments weekly for dialysis.

No Dr was on time, testing facilities were pretty close but they NEVER sent results to Dr office; drs offices screwed up billing; pharmacies would have a problem filling a prescription and NEVER call us' insurance co wouldn't handle referrals in a timely manor; person in a Dr office that did referrals would go on vacation with no one to do referrals; referral person would quit.

Hospitals, more of the same!!  NEVER leave someone you love in a hospital alone!! Bring all of your medications, especially pain meds because you cannot rely upon a hospital to have the staff so that you get what you need, and with pain meds at the time you are supposed to.

An escort running late? I wait a reasonable amount of time and then inquire about how much longer.

Deprived

I was with my wife when she died in a hospital.
