Guest/pete, you reminded me of an older, quite wealthy friend of mine (he has since died). He was a lovely, smart WASP but he was 'self-made' and assumed he would never pay full price on anything. I was with him when he bought a refrigerator. After the deal was made- with a hefty discount, I might add- he noticed that the back corner had a very small dent in it. He demanded another discount. At length, I heard the manager say to the salesman 'Give him what he wants and get him out of here.' I was mortified.
