Well, also, I'm not sure tipping _anyone_ really makes much sense. I mean, if they're being paid to do X... why should you feel obligated to give them extra (and for anyone who's been to a restaurant in North America, you know it's an obligation a lot of the time)? Similarly, I don't see why I should be obligated to give _more_ money to someone being _paid_ to do a job. However, if you're really happy with the service, you might want to do so. I'd call it based on the situation
