I wanted to keep this story separate from my first reply.
When I bought my house some years ago, I woke up one day and had no water. I went out to the pump house and found that the breaker was tripping (something was shorted down the hole). I was travelling quite a bit at the time, and arranged for a well water outfit to come out on the weekend to fix it when I'd be home. The next weekend the guy didn't show up.
I travelled again the next week, so we rescheduled again for the next weekend, again the guy failed to show up the following weekend. We rescheduled again for the next weekend.
The next weekend they were supposed to arrive at 10 AM. They didn't show up and I called, they were running late and would be there at noon. Didn't show up at noon, called him, said they were still running late and it would be 2 pm. To make a long story short, a well service truck pulls into my drive at 7 PM. Two kids, one 13 and the other 14 jump out. It seems the kids got lost driving to my place, compounded by the fact that they had to take back roads all the way, because neither of them were old enough to drive. A minute later a guy pulls into my drive in a fancy car. He climbs out and comes over to greet me. He has shiney rings on every finger, starch pressed shirt and slacks, fancy boots and hat and smells like a french #$&*.
Obviously, alarm bells are going off in my head. I show him the well house and pump controls and he asks if he can borrow my multi-meter to check the electrical. He does a little checking and then starts saying that something isn't correct with the power feed to the pump controls. he can't figure out that when he checks between the three wires, he has 220 between two of them, but then only 110 between one or the other and the common.
I'm smart enough, so I ask him "what's the deal slick?", before I get ready to send him packing. It turns out that he was a bail bondsman and his brother, the "well driller" was running late fishing a pump out of someones well after the homeowener backed over the well head.
Smartly, "slick" decided we'd wait until his brother arrived. Thankfully, his brother was pretty sharp and found a short in the wire 40' down the hole as we began to pull the pump. We fixed it and put everything back together. We decided that they'd come back on Monday and pull the entire length and replace some pretty rusted pipe sections and string new wire to the pump.
I never saw them again. I also was never asked to pay a dime (I was going to pay after all the work was complete.)
