My uncle is the notorious family cheapskate. His house is just about falling down from lack of maintenance. When a hole wears in the carpet, he throws a remnant over the hole. Why pay for new carpet? His best trick, though, is that he buys old, going in the bin ground beef. He lives in a very small town, and the manager at the grocery store knows that once the ground beef is so old they are pulling it back out of the case, if they toss it in the freezer my uncle will come in and buy it for something like a buck a pound. Then he makes big batches of chili with it. He's been doing it for years. And yes, he does occasionally try to feed it to a guest. The smell is supposed to be tremendous.
To give him credit, though, he is generous to a fault with his daughter and her children. He has scrimped and saved his entire life and now she spends his money like it's going out of style. ("Dad, can I get a ride over with you? Can we stop at the grocery store on the way home? Oops, I don't have the money for that. You're buying? Good!") Even my kids see through her shenanigans, but he just won't let his grand kids go without.
