When I smoked (decades ago), I used to hate it when people would bum cigarettes off me all the time. It was usually the same people doing it, and they would always say something like "I only smoke occasionally", or, "I'll get you back later." They'd never get you back later, because they never had cigarettes, and if you kept count, they probably smoked as much as a regular smoker. Back then, cigarettes were a lot cheaper - even though they seemed really expensive at the time. I have no idea what they cost now, but it must suck even more to be handing out cigarettes to perpetual moochers.
