Don't be afraid to walk is really good advice and remember the girl you are inside is a whore she is not your girlfriend. An hour before you arrived she had a cock in her mouth and an hour after you she will have another one. Watch out for scammers not all that glitters is gold.
If you see she has black under her nails she will be a crack head and if you see needle marks then she injects both cases just walk.
