I would have thought an agency wouldn't send a girl round if you sounded drunk. You get the "Won't see anyone who is under the influence of drink or drugs" line on some AW profiles too.
does it not depend how much drink you have had, a few years ago, had booked an escort for an overnight, while I waited for here, had a few beers, told her I was in the bar, and what I looked liked
1 hr later she joined me at the bar, and she here self had a few drinks, there wasn't any issue with me having dome drinks, took her gear to the room, and then we went out for dinner. where we had a few bottles of wine, I managed to perform, and so did she
