Got another one. While putting my wife through her undergrad, then Master's before returning to school myself, I worked at a Mexican restaurant in Knoxville. Manager fired me one night. He was being a bitch, so I threw my apron at him. I didn't expect 15 pens and 40 coins to turn into restaurant, break room shrapnel.
The next day, I quickly obtained a temp-to-perm job at Whirlpool. I was to train for a month, then fill in for those on vacation. Something that should have been easy was incredibly difficult. Contractors building housing developments would call to order appliances. I had to be able to determine which appliances, with certain outlets, and certain product numbers, go where. It was FAR more confusing than it should have been. I show up on Day 2 and their all, "Congrats! You're on the floor!". I barely knew how to answer the phone at this point. Cool. I'll just do my best and wing it. First call. 8:01AM. "I need 34 units of the T34 model with outlet codes xyz." I mean, I'm typing b.s., but it's nowhere close to how confusing this was. I put the guy on hold and just leave. Later that day, I talked my manager into giving me my restaurant job back.
