A while ago, I was charging at a highway stop, so I decided to quickly get something to drink at McDonald's. I just asked ordered a drink, nothing more. One lady started preparing the drink and put it somewhere behind the counter. I was right there, but she didn't hand it to me. I asked if she could give it, as it was the only thing I had ordered. She mentioned she was not allowed to hand over the order to customers, and she was waiting for someone else who was allowed to. It took roughly 10 minutes before I had my drink, it was very frustrating, especially for a "fast" food chain.
