Unlucky leave it at that?
I'm not going to say it is a personality thing since I do not know you nor anyone else here. Let just say you are unlucky and shit happens. There is no indication at least to me there is a problem with how how you act.
There are many girls that get barfine ahead of their shift but continue to go to work since the customer might not be coming until later. So the girl works like O. T. To dance while dancing they get drinks from other customers. She is still working for a living to line up customer for the future?
There is no way for many customers to know unless they ask before hand? I'm sure after the flak he got now he will be asking sooner than later? Sure there is a chance she might just be saying this not to go with him for some reason? Further conversation on his part might be to simple ask her " when is your barfine coming, will you be available tomorrow"? Further question would give the answer that is how I would address it?
