Hmmm..... I thought she was reasonably hot looking. I have more of an "Asian persuasion" so she wasn't "ideal" in my book, but why a big fuss over this ? She did her job reasonably well and the guys liked the way she looked. What's wrong with that ? Normal men are "designed" that way genetically. I seriously doubt anyone from PP IV went out and bought an engagement ring for her. There is nothing "shallow" about being physically attracted to someone of the opposite sex. Harmones make that a pretty "normal" thing.
As far as depth and character, how do you know she does not posess those qualities ? I personally didn't have a philosophical conversation with her, so I won't judge her personal qualities by her outward appearance. I think you should be careful about judging a "book by it's cover."
I'm not jumping on your case as I feel like your heart is in the right place, because of some of the things you said, but the fact that you pretty much agreed with the opinions of some of the other posters that this particular individual is a "slutty girl." I know what the term means and there is no proof that she is like that.
Stereotyping is a necessary evil in some situations, much like "assuming" but she could be a really nice girl with a husband who flirts with her customers to help bring in more tip money for the family. I am not saying that is the case, but you never know. It's something to think about though....
