As a server myself, I have to thank you. It sucks so hard when someone is trying to place orders and talk on the phone. It wastes everyones time. If you do this, understand that servers have to interact with people everyday and although you may not think of it as a personable encounter, we do. We want to help you and see you smile, just like and other good person out there. I know some of us are dicks, or stupid, or a pain in the ass, but that doesn't mean you have to be. We are servers, but we are still people.

TL;DR: Thank you.
