So here’s the setting: you’re in a (busy) gas station, prepaying for gas for your car that’s parked at one of the gas pumps. The cashier sets up the prepay, you go outside, and get distracted somehow. Say you suddenly meet an old friend at the next pump. You spend 5 or 10 minutes chatting with them, exchange phone numbers, and having been completely distracted drive away from the gas station without pumping the gas you’d prepaid for.
A few minutes later, you realize what happens and go back to the station to explain the situation to the cashier. What do you expect to happen?
