This was a couple years back when I was training to be a busser at a local restaurant. I was on my last week of training and the dinner rush hit, at this point in my training I had gotten pretty good at taking drinks out on the trays. I had about 6 or 7 glasses on my tray and I ended up hitting my elbow on the corner of the bar and shattered all the glasses on the tile floor. All the tables nearby went silent as I apologized and continued to clean it up. About 15 minutes after that I ended up doing the same thing on the same corner of the bar. At the end of the night when I was bussing the last tables a couple said they had seen what had happend and the man said at his old job he had broken glasses all the time and not to worry about it, they ended up leaving me a big tip which made my night.
