This, for you, is like so big for someone without social anxiety. As someone who also does not love crowds, I feel like what you are doing here is the equivalent of skydiving. So Yay for you ShyKoala.

P.S I waited tables in college and the first day is the hardest because you don't know how it goes yet. After a while, there are a limited number of orders and you only have to say a limited number of things and you can almost do it on autopilot.
