There are so many posts on this board about service, and so many about tips - and most of these posts are from US posters.
I am in the UK. I do not really notice service unless it is appalling; I have no gripes about plate clearance or bread, or water... and the issue of tips is a non-issue. Servers get paid at least the minimum wage and anything I leave as a tip is an optional extra.
So I'm wondering whether the (apparent) US fixation on service is due to the way it is paid for? Would people care so much about whether their glass is refilled or their plate cleared if the price of service was included in the price of the food?
