Just curious, especially for outcalls.. do a lot of providers throw in a latenight surcharge on outcalls, or just plan refuse to see people (roughly, I know every provider is different)

on their websites. You are right that every provider is different. Many won't see people late night. I haven't heard of a latenight surchage, but I am sure somebody out there charges one. I have seen the opposite. I knew a gal, who used to advertise a special 3 hour rate between 4 am and 10 am.

If you are trying for a last minute appointment and you call one at 2 in the morning, you will most likely get ignored. But some gals can be available in the middle of the night if it is planned well ahead, especially in cities like Las Vegas, (which is a 24 hour town anyway)

with a lot of ok's on p411 or TER white list refs how are they going to screen you. Start calling/emailing your refs in the middle of the night? Not going to happen. Many providers are single moms, you think they're going to leave their kids alone.Finally many providers won't make outcall appointments to private residences until they've seen you at their incall or a hotel. For top providers it's always about their safety.

Now if you want to try seeing someoone from BP with no reviews, that's a whole other story.  

my experience was it gets riskier (for things to go wrong) as the night gets later. I would guess it's the same for providers so I wouldn't bother with late nights (after 10).

I don't have any problems going out at midnight or so if the gentleman gives me advance notice.

I've had gentleman let me know they were flying in from another state and would arrive at their hotel around midnight or so and wanted to see me shortly after they arrived.  I have no problem with those types of requests.

A guy calling me at midnight that I've never talked to before and asking me how soon I can be there - I will usually tell him its just too late for me.   Not even getting into the screening issue, if you are calling me at midnight, I have probably totally settled down for the night and do not feel like jumping in the shower and getting dressed.

Not to mention most of the last minute callers after 11pm are usually guys who have been drinking and I really dont want to show up somewhere to meet a drunk.

It does get riskier - there are some neighborhoods that are not safe for a single female to be in after dark.   Not to mention police are out more looking for drunk drivers.
