> If anything they're a hindrance.

Absolutely. As a brit used to waiters and waitresses in the UK and Europe generally leaving me alone until I ask for something, I find the constant fawning interruptions from American service staff cringe-inducing.

A refreshing aspect of US culture is the lack of a historical class system and associated cultural baggage that we have in the UK. So I find it so strange that once you step into a restaurant you are forced into this weird servant/master cosplay where you dictate the server's livelihood based on how you happen to be feeling that day and the resulting whim of your pen writing on the tip line.
