The one thing that annoys me about waiters today is that the majority of them like to come ask you how you are doing 5 times or more AND always when you mouth is full. I hate that crap.
Best service I ever received was the invisible waiter. Anytime I needed something it was there. Never had to ask for a thing and never even noticed he was at the table doing his job. At the end of that meal I left 30% and told his manager what a great waiter he was. That was the biggest tip I ever left.
He was a breath of fresh air.
Same as it ever was.
