Way back in the early 1980's I put a "Welding" ad in the local shopper paper. Huge mistake. Many responses from financially challenged rust bucket auto owners needing their rust welded back together. One woman called every week for a month about the drivers door falling off her Pinto. And when the ads in print, you can't kill it, it just keeps on giving.
Got a call from a hermit looking guy who was vague on the phone, ended up stopping by in his 1950's rust bucket Jeepster. He opens the hood, pulls out the dip stick. The "washer" spot welded on it that determines how far it goes down in the tube broke free. He asks "how much to weld it"? At this point I'm seeing nothing but humor in the situation, and I say "I can TIG weld that no problem, TEN dollars" which was not even worth my time. He says "I can get a good one at the junkyard for SIX". I said "Happy motoring"! and went back in the shop and locked the door.
