RE: Tipping on Buffett's
I'm confused. In the hotels I've used that have breakfast buffets, they are complimentary. In some of them, you even bus your own table--deposit your tableware in some sort of a collecting bin as you leave. For what would you be tipping? And since you paid nothing, what would be the appropriate amount? Personally, I don't usually eat much at these affairs. Maybe a cup of coffee and roll or some fruit (I usually sleep fairly late and, when I'm travelling, I'm already looking forward to a good-sized lunch). At market rates it's worth maybe a couple of bucks. Assuming I wanted to tip, even $1 would seem kind of extravagant for the minimal service and I'm not sure where I would deposit the tip anyway (like I said, I often leave the table bare and there's no one circulating in the room to collect any money I leave on the otherwise bare table).
IMHO, this is really a different situation than the buffet-style restaurants discussed in the other thread where someone clears off your table, brings your beverage and generally facilitates your meal. As I said in the other thread, at those I usually tip 10% since I figure I'm getting about half the service I do at a regular restaurant (and the servers cover--and thus benefit from the tips of--a far larger number of tables).
