Okay, so when I was working at AutoZone as a store manager, I had a customer come in and buy a fuel pump that day. And he had gone home, he tried to connect it, and he came back to return the fuel pump. Well, I asked him what was wrong with it, and he said, I couldn't get the wiring was wrong. And that specific fuel pump I had already read up on, it was a, there was a mix-up in the wires, so you had to actually switch the plug out in the wires. So I actually followed him to his house, and got up underneath his truck, and I installed the wires correctly for him, and I mean, we fired it right up, and he was very satisfied after that. So I ended up gaining a lifetime customer because of that.
