Waiters don't want to be called waiters - they want to be called servers... but have you noticed that these servers don't actually serve you the food? It's always someone else that you've never seen up until now. You get to the restaurant, get comfy with your "server", maybe get a drink or two... then here's someone you've never seen before in your life handing you a plate full of whatever you ordered that hopefully isn't poisoned. That guy or gal, to me, sounds like the Server. The customers (or Patrons) should be the waiters because we're the ones waiting for our food to get there.
