19. When You Forget How Polite You Are
Whenever you're having a fun day out at the movies or in a restaurant and the server will say "enjoy your movie/meal" and you reply with "thanks, you too" and you cringe at your mistake and hope that they didn't' hear. Idiot. As much as you were going for being polite and wishing them well, you've just rubbed it in their faces that they're currently at work and having to serve the general public - which if you've ever worked in retail, is the worst thing in the world. It also applies to when people ask you how you are and it goes around in a vicious circle of "fine thanks, you?" It's not that you weren't listening per say you just always like to make doubly sure that people are genuinely fine.
