My way of thinking towards serving staff is mostly the same as to everyone else: "Here's a person, I will be polite to them".
On a semi-unrelated note, I feel really really badly when people pour my water/drink, probably because it's servile and I am really averse to it (I don't like thinking of people as inferior). Perhaps surprisingly, I don't mind waiters bringing me what I ordered, I guess it's because that's expected and accepted, thus it's not something that shows (or forces) inferiority.
