answer:While I am of a camp that tips 20% in a restaurant, 25% or more for excellent service, I don’t tip housekeeping at a hotel at all. Table serves that merits a higher tip is attentive but not intrusive, not overly familiar, and prompt but not pushy. I like my plate cleared when I am down with my meal, but give me a pause; I don’t want somebody swooping down as I eat my last bite. And I don’t want the check when the plate is cleared, but I don’t want to ask for it after two cups of coffee.
