A couple more since this thread started...
I bought a 62 Caddy for $1500 because the guy said it just died one day and he couldn't get it started. When I was negotiating, I noticed the distributor cap had popped off and was crooked. After I gave him the cash and he signed the title, imagine his frustration when I put the cap back on, fired it up, and drove it home. Fix = free.
I snagged a 74 maverick for $300 because the guy was frustrated with the electronics. He had replaced the solenoid, the alternator, the starter, and the battery, and it just wouldn't hold a charge. After jump-starting it and getting it home, I realized he had put the alternator wire on the wrong side of the solenoid. Fix = free.
In my current job (tool repair at Home Depot) I have amazed people with my "talents." They pull a lawnmower out of the garage in the spring and it won't start. I pull the bowl off the carb, drain the fuel, run a wire up through the jet, put it back together and it starts on the first pull. Of course they say they ran it dry last year, or used stabilizer, then I show them the tablespoon of water I got out of the bowl.
Just two days ago I had a guy bring in a top-of-the-line Honda mower and said it won't start. I pulled the cord and water shot out of the muffler. WHAT ARE THESE PEOPLE DOING? ![](/media/img/icons/smilies/googly-18.png)
Another one came in... it was an old Bolens string trimmer that would only idle. The guy had bought a new Echo but wanted to fix this one to take to camp. The muffler was just packed with carbon and oil. I grabbed a drill (which already had a 1/2" bit chucked up from another project), drilled a hole in the muffler, ran great. He asked me what he owed. I told him that we charge $60/hr and this job took me 35 seconds. I said "you owe me a handshake."
This is why I love my job. I get to make customers happy by simply using my analytical brain. One thing I will say about Home Depot... they recognize customer service. No boss will come to me and say, "you didn't follow procedure," or "you should have charged him the minimum $15." They say, "thanks for kicking ass and making a customer happy."
