Is it normal that I'm nervous about starting my job, even if it's just a Subway? I just have this feeling I'm going to mess up. What if I forget a special? What if I mess up someone's change? What if I don't notice a spot that I should clean? What if my coworkers think I'm weird because I'm shy? I keep thinking of all these ways I might mess up, but it's just a Subway! Shouldn't that be easy?
