So I see dustmen/garbagemen are pretty much the same the world-round Mind you, if I had to be handling people's stinky garbage all day long, I'm not sure I'd be smiling all the time either.

Maybe because I'm a girl but anytime I've had encounter with them, they've been pretty nice (like when I'm running to catch up with garbage bags cause I forgot to take them out)
