Quite a few posters seem to have caught celebs on off moments , and obviously there will be times that people would rather not be disturbed, but I suppose it is how they deal with that situation that matters.
Last night I saw Rory McGrath in town , and he was having a private conversation on his mobile. A drunk guy went up to him, put his arms around him and took a selfie, while Rory was still chatting on his mobile. To his credit , he remained unfazed and carried on , but I thought the drunk guy was pretty rude. I suppose celebs come across this all the time, and Rory seems like a pretty nice guy , but I can imagine some celebs being rude back in such situations.
