This is how I feel about getting my water refilled or my empty plate taken away at a restaurant. Nowadays, the wait staff always interrupt my conversations to ask, "Are you finished?" or "More water?" or whatever. It used to be part of the art of serving in a nice restaurant to notice when someone's coffee cup is empty and silently and unobtrusively refill it and disappear. And the customer would cross his or her knife and fork a certain way on the plate to indicate, "I'm finished with this," and the server would appear and whisk it away without the need for conversation. The good ol' days. I miss that!
