I have seen a middle-aged lady fitting your description. ~5'5" including the high heels. Another description I would add is that her face looks like it has had plastic surgery, probably a facelift and nose job. I've seen her walking around the room wall to wall then back usually hustling for $1 tips because virtually no one will buy her drinks or take her up. For me, given the 4 hours round-trip driving to TJ and back, the cost of gas, the parking, the taxis, and ancillary expenses, I now will not let girls hustle me. I go to TJ to choose who to tip, and who to spend money on, not the girls choosing me. If I have no interest in a girl, there is no reason I should or want to tip them at all. Like you said, our resources are limited and we have to choose wisely. Also, tipping the girls you don't like only encourages more of the same type of girls in that environment. I want to reward the girls I like in order to encourage more of the similar type of attractive girls to work there and behave in the manner I like.
It's too bad these older chicas did not have a plan to save money, or study, and to get out of the profession. In a way, I do feel sorry for them. But, in some other ways I do not because some girls can be real cunts.
Besides the old bar girls, there are the really old hag messed up hoes you see walking around on the streets occasionally. You can tell by the way they dress that they are hoes, and by the face bone structure and eyes that some of them used to be decent looking, but wrinkles and fat have taken their toll.
Last week I saw something totally disgusting and scary. This old hag in her 70s was stumbling around the taco stand without wearing any underwear. Don't know if she used to be a puta 40-50 years ago.
