Most interesting thing that happened at work?

Once orders were running behind so deliveries took over an hour to get to people. One lady complained about the wait and our manager said if our driver isn't there in 6 minutes then she will get her next order free. The driver gets there in 5 minutes. The lady's wife comes up to the store with the food, speaks to a different manager and called the other one fake, got a refund, then continued to complain. After all of that, she called us back and complained even more after she already got a refund and everything. She was also mad because she lived down the street, but it's also like if you are just down the street and don't wanna wait, then why don't you get up and come get it yourself? Customers man 🙄
