As a waitress/waiter would you accept Facebook Friend Requests from Customers?

[Criselle]

I'm a waitress and this guy (whom I've only seen once and really only talked to for less than 2 minutes before I had to go) keeps sending me a friend request on Facebook. He just said "You're beautiful," we introduced ourselves, asked where I went to college, and not much else..

He looked to be about late 20's...

If you were a waitress/waiter and in this situation would you accept a customer's friend request? Unless I saw HUGE potential for a relationship, or if we really became friends, I wouldn't bother accepting it because I think it's unprofessional and can make the workplace awkward if he comes in again...

What would you do? Would you/have you accepted friend requests from customers? Just curious Thanks! (:
I honestly didn't reveal any information besides my first name.... not even my last name which scares me about how he found me... I didn't even say what school I go to or anything, just my first name, so...
