I was working on a fairly new ice cream coffin display and had to flip the evap fan panel up to have a look and found an air drill with a long 1/4 inch bit. It was pretty wet where it wasn't frozen. Lots of rust. Someone at the factory was thinking about the wrong thing on a friday I guess.
The store manager saw what happened and rushed right down from his office to check it out. I was just a rookie then and let him take it.
A few weeks later he asked my boss if we could fix it for him on store time. The answer wasn't too pretty.
