So today at work it was my first day in scanning and I accidentally broke the entire meat department. Scanning is the person who controls all the prices in a store, and I somehow deleted all the prices for all the meat, so they couldn't put any new product out. It was a great way to start a new position! still don't know how I managed to delete all the codes themselves though, what I did was apply the new prices too early.

What oops did you have recently? Or talk about a time where you messed up and broke everything.
