Hey Pandas, Tell Me About Your Stupidest Customer (Closed)

When I was in my 20s, I worked as a cashier in a grocery store during the summer. One customer came to me with a watermelon yelling at me that I sold her a bad watermelon and ruined her family lunch. She was referring directly to me as if I grew it, transported it, put it on in the store, then in her basket, and took money from her just to make her life miserable.

I had a customer who didn't understand the keyless system of his new bought car. He argued with me for 10 minutes straight why he recieved a key... I told him several times that "keyless" means he doesn't need a key to start the engine but still needs a key to open and lock the car. He eventually figured it out after my manager explained it to him AGAIN exactly AS I DID.

In either 2006 or 2008 there was a power outage that affected the entire city and all the neighboring towns. The power was out for almost a week. I worked at a gas station 20 minutes outside of town and people would show up hoping to buy gas. We were open but unfortunately we had no power either and some people didn't even have enough gas to get back to town. People were desperate and I understand that but one person I was was so stupid he put his lips on the gas nozzle and tried to suck the gas out.
