ME: Hey, do you know where the nearest Starbucks is?
HER: Uhm sorry, i already have a boyfriend.
That would be weird right? Not a single girl would react like that. They would give u the directions, and then u can move on. Did u get rejected when u left that conversation? NOT AT ALL! YOU COULDN"T BE REJECTED!
I haven't asked for the Starbucks but for the Train station, for the Time, for the bank, for the city center and for a pub I've had and "sorry, I already have a boyfriend"" is a common reply over here. Anyway that is not a rejection that is just meeting brain dead scared zombies, so who cares if they answer like that.
