LMAO. In HS, we had a single vending machine. The slot in which the 3 Musketeers bars were in was malfunctioning all of the time. I'd put $.35 in and get the whole row of bars. I'd sell em for $.35 to my buddies and did it for 5 months. We'd often tell anyone who would listen that the slot was broken as you'd put in the money and get the whole row.
Then, a teacher approached me about charges. I said "Go for it, Please I implore you to do that. We've told the Principal, various teachers, custodians and they ignored us." Never heard from anyone again. The slot was fixed shortly thereafter.
