As far as the wait staff being young I think that is entirely do to the make up of the applicant pool. The pay and hours being such as to attract high school students and students at the local technical college looking for some income. Not looking for a job that would support an independent household.

Why only young women applicants? I'd say this is a small rural town that has been largely unaffected by the social justice wars elsewhere. Young men just feel pressure to find young men's type work? Some times the outdated local views of things drives me crazy. Not so much in this case though. Probably a lot to do with this being a small town with little turnover in population. Most families have been here for two to three generations or more. It's funny too how in the local telephone book some very unusual last names are far more common than names like Smith or Jones. Everyone knows everyone just about and the young women working there are the daughters or granddaughters of the customer base. Or classmates [local schools] of the daughters or granddaughters of customers. I'm sort of an oddity with no historical ties to the area.

As far as the young women being so attractive? That I'd have to attribute to the woman who owns the place. It just can't be coincidence.
