Most dancers are freelance employees meaning most clubs do not require the girls to have a set schedule but will usually require you stay between 4-6 hours. Clubs definitely frown upon girls leaving with customers. This is the epitome of why it is so dangerous to do so, but also if a girl leaves (solicits) an undercover - obviously not good. And, if a girl can make money off of a customer but chooses to cut out the middleman (the club) you can see why it is in their best interest to have the girls stay. (not to mention who wants this kind of bad press for their establishment). That being said, it does happen and in this case, where they seem to be friendly aquantiences of many at the club, nobody would ever think Jaren's safety would be in jeopardy.
As for walking to parking garages or taxis in groups, let's face it, that would be ideal but rarely ever happens. I can tell you from my own experiences whenever I work in the F.Q. I always have a doorman walk me to my car b/c the garages are at least a block away. However, I usually have to wait before another host can come and take his post (which you'd think since it's about a 15 minute walk/wait till car comes out of valet they'd have at least 2 available for walks). And not every girls asks for an escort to her car/taxi. I do not believe these guys are allowed to carry weapons so it's merely safety in numbers.
As for background checks, every place I've ever worked at they require you to fill out an application make a copy of your driver's license, etc. I'm not sure if they do a background check but you're certainly known to the clubs. I know I get a 10-99 in the mail to claim taxes so I'm certainly in the system. But the owner's of the Tempations/Stilettos/Scores/Lipstixx are locally owned where as Penthouse Rick's and the Hustler corp have too much too lose so they abide by the law.
And I must also add that in my 10 years of working in the Quarter I have never ever heard of a raid at a reputable club. Ever. I have heard of them on Airline Hwy (Prairieville) but not Bourbon.
