I know a multi- millionaire.
I helped him in 1984 with moving a car from a dealership to one of his business locations.
He said he'd buy lunch. I envisioned at least a prime rib sandwich.
He pulled into McDonalds, ordered a small coffee, the cheapest burger, looked at me and said "Get whatever you want."
When I was selling cars in 1986 a guy that was netting $40,000 per month off a car wash tried to delete the hubcaps off a Ford Taurus to save money.
Sometimes those that have money like to keep their money.
