One possible interpretation:
... maybe the strippers who said they previously worked at Hooters didn't actually work at Hooters, but figured that saying so would be a good answer. Using the Hooters lie first of all moves away from having to admit to having really worked at somewhere that you might recognize, or at somewhere that is more embarrassing to them, or at nowhere at all which is even more embarrassing since it means that their first ever career choice was to not have a sensible career choice. Also, the Hooters lie moves toward a typical male fantasy, a turn-on for the customer, or so the girls will be thinking. Kind of like saying, whether or not it's true, that she used to do some amateur porn or was a cam-girl, and that she's thinking about getting back into it. Certain sexier than saying she's a dish-scrubber for the elementary school board.
I don't necessarily think that all Hooters claims by strippers are Hooters lies. I just thought I'd throw out that possibility.
Another possibility, maybe closer to the truth, is the following. Given, let us presume, that some girls are pretty much destined to be strippers, for reasons such as the lower-class daddy-issues trailer-trash home-lives they grew up in, a few typical high-school-aged choices she made when she was high-school-aged, and a great body and cute face plus a need for ready cash. If these girls are gravitating toward the strip clubs from all their other potential occupations -- whether it's an "occupation" of a work-type situation, or whether it's just "occupation" of her time by doing her nails and texting her BFFs -- then Hooters is simply a quick stop-over. The path is from respectability and brain-work, towards the adult-services industry and looking good. So, of course, good looks become part of the job requirement, and part of the package that the potential employee can offer to the potential employer. They end up for a while at a Hooters or knock-off. However, please note, that doesn't really mean that they were strongly INFLUENCED into choosing stripping, on the basis of waitressing at Hooters. In fact, it may have been all along that the Hooters influences were redirecting her mildly AWAY from stripping but failed to accomplish a full turn sideways in her career trajectory. It may indeed be, that all these strippers who make the Hooters claim did indeed work at Hooters, but only for two weeks or so while getting their shit out of their ex-boyfriends Dodge Dart and moving in with some skank they used to know in Junior High who is stripping, with the intent of going into stripping all along.
In other words, I feel the Hooters claim can be truthful, but in a variety of manners. Therefore, its prevalence need not suggest to us that working at Hooters necessarily helps CAUSE girls to become strippers (although that is a possible corollary; remember, however, that correlation is not causation, and beware that we are moving close to being guilty of the post-hoc-propter-hoc fallacy, of assuming that if stripping comes after something, then it must have been caused by that thing.) Not that there's anything wrong with that. Also, not that everyone in this thread is necessarily assuming that. I am just mulling the possibilities, taking them out to a bit of a logical extreme. So sue me, I'm a Book sort of Guy. :)
In fact, the hottest newbie at the club I went to most recently did indeed claim to me that she used to work at Hooters, along with claiming that she had only been working at that strip club for three weeks. I can confirm that her lap-dances were profoundly annoyingly inexperienced, with all the wrong contact at all the wrong points (kind of like the way Paris Hilton moved in a stupid self-involved sway in the leaked blowjob video tape while failing to contact the dick with her mouth) to the point of suggesting that she had indeed only been working as a stripper for three weeks.
On related subject, I had no idea that there were OTH (Outside The Hooters) opportunities and have, many times, oh so desperately wished there were. Traveling alone, staying nearby, have ready cash to spend, a girl at the end of her shift ... are these experiences of the rushed disappointing and rather sterilized, as though for the hospital sex-services ward, of the manner in which they go in a back room at a strip club? Or can you get some girlsie-boysie satisfaction and kind of play at being her fake-boyfriend for the night, laugh, cuddle, make out? I am in the Tampa Bay area now, home of the original Hooters, and there are several knock-offs. Ker's Wing House, Brew House, Mugs N Jugs, T-Backs (now shut down I think?), etc.. Where should I start my OTH search? :)
