Is it weird to add someone I met through work on facebook?

[Emily]

Soooo I met a guy today who was a customer where I work. About my age, super nice, fun to talk to, and great personality. He's new to the area (moved here from the other side of the country) and is staying with his brother until he meets some people and has a place of his own. If we really hit it off, would it be weird to send him a friend request on facebook? I don't want to seem like a creeper or anything since he never really said "look me up on facebook", but at the same time he seems like he'd be a fun person to hang out with. Plus if he doesn't know really anyone in the area, maybe he'd be cool with it? Idk........what do you think? Should I go for it?
