This happened back when I was about 23 years old in Canada. I'm actually Canadian. I worked there too, obviously. But anyway, I was 23 years old and I worked for a tool rental company. And a customer came in with a carpet cleaner that was defective and he just started yelling at me, telling me that everything wasn't working. And he was cussing the store, cussing me, cussing everything. It was just really irate. And it turns out that the problem with the carpet cleaner was that it was a little switch that he didn't flip to make the carpet cleaner not leak. So he had it flipped open and the carpet cleaner was leaking water everywhere in his house. I told him about it afterwards. I was calm and I told him I understood. And I apologized a whole bunch of times and told him, you know, I'm sorry for the situation. It's our fault. Let me exchange it for you. So I exchanged the machine, but I explained about the button to make sure that he had it up. I didn't tell him that he did, but I said, hey, maybe this one came like that and you didn't notice. So I'll make sure to flip it up for you this time. The button is closed. Don't touch the switch anymore. That way your carpet cleaner will work. He said, yeah, thank you. That's fine. He left a little still mad, but he left and he finished his job. Once he returned, he said to me that he apologizes. He apologized to me, actually, saying that he was out of line and he shouldn't have acted that way. He explained to me what happened beforehand, which was that he went to McDonald's when he left his house to come over to our store. And he had actually had a bad experience there. They treated him really bad, so he brought all that anger to me and he just vented, really. He was just venting and he was actually happy that I wasn't able to react to him, you know, because that way it would have been a worse situation. But that's how I handled it. He liked it. He ended up being a good customer of ours after that. And that's what happened.
