Should he leave his number on a restaurant receipt?

I'm sure that any girl that has ever worked in the food industry has gotten the ol' phone number on the back of the bill ploy. So, for curiosity's sake, does this tactic work? Or is it cheesy no matter how attractive he is. Should he man up and ask for your number instead?
