I have a bunch of friends in jobs where they deal with the general public day to day, and they all say the same thing: until you do a job like this, you have no idea how many doofuses are out there, how dreadfully they will behave, how entitled they will act.

Sounds like you are confirming this opinion for me.

I guess in a way, servers have to be like an army, supporting each other, with a little kindness and thoughtfulness against this battalion of doofuses. Otherwise, the whole army loses the battle together. :(
