I hate it. It disrupts the meal and it is so loud you can no longer converse with your tablemates. The waiters that I have asked about it, hate it also. They do it because they have to and they smile while doing it because that's what is expected of them. Have you ever had a waiter come back to your table all giddy and smiling saying "gee, that was fun, I can't wait to do it again"? No, they come back acting professional and pick up where they left off.
