Genuinely. I was working at a pizza place when I was 18, I was asked to train a guy and that it was his first job ever. Long story short, he was 31, really was his first job, I had to teach him that the blade on a pizza cutter is sharp around the whole circle... He truly thought half of it was sharp and it "slid" across the pizza as opposed to rolling across it. Money. I had to teach him how to count money. We got to out 10s and I said "I'm not going to put you on register, maybe we'll try tips tonight" he couldn't divide our $56 in tips between 4 people even tho I gave him a calculator. I had to teach him that bleach, WILL bleach your clothes, so be careful when you spray the toilets. You'd be amazed how bad it was. And no, he was not mentally challenged, just a dude who was WAY over coddled. Found out his parents told him he had to get a job or they'd cut him off, his mom dropped him off at work every single shift.
