I know what you mean but 98% of the time you wont get trouble of them, if they are rude to you, just ignore them, that's my advice.I once was stopped by a man who asked me the time, I said "Sorry mate, I'm not wearing my watch!" (I never wear them) He got mad and shouted "BAh! F*ck off then!" I made the mistake of replying "Yeah you f*ck off!" ('cause I wasn't in the mood for putting up with nonsense at the time..) anyway he grabbed my arm and swung his fist at my head!
It didn't hurt 'cause he didn't hit me hard, I think he was drunk! Anyway when I think about it now I should have just ignored him!
