Would you estimate on average Las Vegas strip has between 1,000 or more hookers (they like to refer to them as working girls) working per night. And remember each one no matter how sexy or frightening has a pimp ('daddy'-always listed on their cell phone and when calling the ass) and pimps normally control only one to very rarely two to three girls--that's a lot of jackasses. You were there long enough to get a pretty good sense of the environment and spot them or observe the typical profile (i.e. Normally alone and often in pairs [part of the game of setting up dumb men but the drunks are the big fish for trick rolls = in room theft/robbery in which they make as much or more money than hooking] with ever present cell phone in one hand and small over shoulder purse and always smiling--they seem to be the happiest woman in the casinos, often mismatched shoes or purse, various outfits from old school street look to cheap Wally World Cosmo look alike, walking thru casino floor randomly or sitting near guest elevators at slot machines and last, but not least, sitting at the 'hooker bar'--every casino has, at least, one well designed and notorious hooker bar--even all the five star resorts. Also, if the girls smoke it is almost always 'NewPort' cigs a crazy part of the pimp culture all over the US. I could go on and on--I too have stories). Sorry to overdo the above--for educational purposes.
