I have had friends who smoked cigarettes and there were always guys mooching cigarettes at the local smoking gathering spot. I gather this isn't true with cigars?
I'd be shocked if a random stranger approached you to bum a cigar anywhere. Cigarettes are cheap and people have them by the pack so it's not a big deal to bum one but cigars are a whole different smoking experience entirely. Friends bumming cigars on the other hand..
