The customers really are the best part of the job. I spend way too much time just chating up with the guys dropping of jobs. But some of the call I've gotten just stick in the mind.
One lady called up and asked if I could fix her "water well". ( As I write this I realize she may have been suggesting something else entirely.) I asked her what kind of a pump was it and what problem was she having. She replied "It's not a real well, just a decorative one." and that "It probably just needs some nails."
A gruff old man called up and asked if I had some non-detergent 30W for his lathe. I told him all I had was 10W spindle oil and 90W gear lube and asked would one of these do. He became pissy and said he was "sure" I had a big barrel of "lathe oil" in back and why couldn't I just give him some?
