I can laugh about this now but at the time it was horrid.
I had a part time job as a waiter in a restaurant, I was ok at it but always nervous that I was gonna get stuff wrong. On a busy Saturday night I was carrying three plates of food and I slipped over in the middle of the restaurant. The whole place went silent and then a few people started laughing. I was freaking mortified. I went to the toilet and started crying.
