Ugh, I hate it when servers mock my stutter! Yes, I get that they probably think I just made a one-time stutter, they don't know it's an issue every day. But it's so embarrassing, especially when I'm with other people. Once I was at dinner with 5 other people and a server mocked my stutter back at me, and I just froze. I wish I could answer back, but I never have yet.
