I wanted to like this, I really did. And maybe other episodes are better.
The first woman was/is a CPA. She went to buy a shirt in a thrift store that was $10. When she got to the front, she told the guy that she only had $5 in change and could he lower the price for her. When he said no (as far as I know, stores can't haggle prices), she scooped up her change and said that she would "go elsewhere", as if the guy had been rude to her (and her was actually apologetic and polite). I couldn't after that.
Being frugal or even cheap out of necessity is nothing to be ashamed of. Saving money because you are on a tight budget is nothing to be ashamed of.
But her cheapness seemed to be for the sake of being annoying.
