I've heard the "...this is Las Vegas" before, but that's only for tourists, there are plenty of options here. I recently restarted hobbying a year+ ago, living in vegas - using mainly tryst and PD for prices, staying in the 3-4 range for incall, then branched out into the AMP market here.
Some charge the same for outcall, some just want uber/lyft, a few charge a little extra.
The range is out there and really depends on what you want.
200+ tips - that's shady, get everything agreed up front over email/sms or find someone else. I also veer away from a deposit before even making an appointment. A few on tryst, want a pretty big 50% or something to even make an appointment, someone with no reviews anywhere, that's a no. Small deposit for a room, I'll do if there are reviews or if it's not insane. I'll think about doing a small deposit to hold an appointment time. But still have to be careful out there.
