I had a great-uncle who was stinginess itself.
He had had a job as the senior accounting manager of a large company and had an extremely good salary for the majority of his life, but lived in a tiny apartment filled with the cheapest second hand furniture he'd been able to find, a 30-year-old TV he'd bought in the 60s and 3 light bulbs. The surfaces of tables, shelves and flat parts of other furniture were covered with old newspapers, because "in that way you don't have to waste money on cleaning products". The day my grandmother suggested that he hire a cleaning lady, he got into a fury and answered that she should clean his house for free instead, to show some gratitude for the fact that he had supported her when she was a child (their father died when my grandmother and her siblings were very young, and the two oldest brothers had had to work like crazy to keep a roof over everyone's heads and put some food on the table).
Whenever he wasn't working, he'd wear exactly the same clothes all the time, and only ate a sandwich and the runniest spinach soup imaginable once a day. On weekends, he'd make "surprise visits" with relatives and friends at lunch time, and would invite himself to eat while asking people to do his dirty laundry because, apparently, his washing machine was always broken and he couldn't find a good repairman. I used to hate his visits, because he'd sit to eat at 12 and wouldn't stop swallowing food until well past 4 o'clock. Then, he'd ask to take all the leftovers home "because food is expensive and you know I'm poor", but got angry when people gave him actual leftovers - he wanted the newest and best they had. He also had the cheek to ask family members to iron his clothes while he sat to watch TV, and always left without even a miserable "thank you". He took so much advantage of people, that everyone started to go out on weekends so that they wouldn't have to put up with him, which frequently elicited irate "you are all such ungrateful bastards" tirades.
On a sadder note, he had a son with a coworker and, to avoid supporting him, he accused her of being a whore and said that the boy wasn't his. To make matters worse, he always refused to take a paternity test and my great-grandmother, my grandmother and her sisters had to take it upon themselves to make sure that the child didn't go without, because his mother already supported her elderly parents and they barely got by with her salary.
He was also notorious for refusing to help relatives in need even though he'd made a fortune in stock-trading, but he still had the cheek to get furious whenever someone denied him anything at all. Eventually, most people ended up hating his guts, because he was incredibly abusive whenever people tried to prevent him from taking advantage of them.
However, his undoing came when, in his late 70s, he met a couple of sinister white trash criminals. He had been in jail for drug-trafficking and was a "mechanic", but was hired as a gardener, and she was both his "housekeeper" and "special friend". Over the following 10 years, they cleaned his accounts, sold his three houses from under his ass, brutally mistreated him and eventually, disappeared with the money. Two of my mother's cousins took pity on him and paid for a care home while they were trying to recover what had been stolen (very little was ever recovered), and he still had the nerve to complain about the fact that the care home wasn't luxurious enough, and accused my mom's cousins of "being greedy" and "trying to fleece" him! Also, the old piece of shit got angry with them when they told him how the "housekeeper" had gone to prison, and said that they wanted "to steal his happiness".
Not strangely at all, when the old fart kicked the bucket three years ago, only 3 people attended the funeral.
