Doug:
Here are a few. They all happened to me.
When asking about a car For Sale that was not nearby:
"Yes, it's the original color" (Truth: Original color was Beige, now it was Bright Yellow.)
"All the body parts, engine, and dirve train are original" (Truth: the numbers on the hood did not match the car number and both fenders were obvious replacements.)
Then there was the "Buyer" who gave me a down payment on the Pagoda I was selling, "I'll have the rest of the price to you by FedEx next week." (Actual: Two weeks later he asked for his "non-refundable deposit back.)
How about the mechanic who said, "It'll be about $750 for the whole job". (Actual: $1,800, Well, we found a few more problems."
A major parts supplier: "We'll ship the part in two days. You'll have it less than a week." Actual (when asking about the status a week later: "Sorry, we were out of stock and the supplier in Poland is too busy to fill the shipping container. My boss has to go to Poland and fill it himself. It's going to take about three months."
I'll stop here, it's too painful to think of more.
