Incredulity, I haz it

This isn't my story, it's Sally's story, but since my other posts this week have been Sally-related I thought I'd run with it. Sally met a stripper at the Atlanta airport. Wait, that sounded bad. Sally had an hours-long layover in Atlanta and spent it at the Houlihan's bar, where a young woman sat next to her. Sally asked the woman what her job was, and the woman replied that she was a model. Over the course of their conversation, it turned out that she wasn't so much a model as a stripper. Now, I'm not judging her, we all have our talents. But here's where the story blows my mind: the stripper told Sally that she strips with her mom. Not just that she strips with her mom, but that they make more money that way. Wha-huh??? It raises a number of questions, certainly, but one of them has to be this: how did they stumble upon that business model?!?
