This is very subjective - what is 'refined' to you might be stuffy to me. I have friends who have staff, and for the most part they are friendly, cheerful, and good at their jobs, but others may find them overly familiar, they don't typically wear formal suits, nor do they genuflect. The word refined doesn't have a clear meaning, I prefer service to be thoughtful, and that can happen in any setting (for example, a mid level hotel in India where noticing me absent from dinner, they sent up hot tea, lemon, honey and a home made remedy.
