Ruby Tuesday

I took The Little One to Ruby Tuesday's on Saturday for lunch. Supposedly, daddy/daughter quality time but she was on somewhat less than perfect behavior for some reason. Anyway, my extremely pleasant waiter at the end of the meal said "Thank you. It was a pleasure to serve you." and he stuck out his hand to shake it. Of course, I extended mine but that struck me as very odd. What kind of waiter, or waitress for that matter, shakes their customer's hands? Maybe he used to sell cars or something.
