In the early '70s a guy brought his TV to my dad's shop for repair, loudly proclaiming "It's not a bad tube; I tested them, and I'm an engineer, so I know what I'm talking about." (Dad and I exchanged a knowing glance.

) After Dad replaced the faulty horizontal out-put tube, we gave his TV the normal service, cleaning the tuner etc. Dad left to do service calls, after instructing me to not close until the guy came to pick his TV up, as he had also stated he wanted the repair done ASAP...
About 5:30 (we closed at 5:00) the guy calls. I tell him his TV has been repaired. He asks what the bill is, and I tell him $36. He says he will be right over.
Fifteen minutes later the guy bursts through the front door, pissed off as hell!!! He demanded to see the bill, and then proclaimed we were ripping him off: "You didn't pay $12 for that tube!!!" "That is the suggested retail price from RCA", and I show him the price list. "Well, this is a rip-off! I could have fixed it myself, but I didn't have the time" I'm biting my tongue now. I tell him if he wants to leave with the TV, he will have to pay the bill, other wise he will need to come back the next day to discuss it with my father. The guy storms out, even more pissed off.
He came back the next day, and Dad went over each of his complaints one by one. "Do you think that MY time has no value? Do you think we have no expenses? Do you think it is wrong that we make a profit on parts?" (the profit margin on women's shoes is MUCH greater than we had for vacuum tubes) No matter how Dad tried to explain the realities of small business, the guy felt abused. Of course, he was drawing a steady paycheck as a government contractor...
