Thrifting His Own Wardrobe
J.P.'s former Secretary told of how the billionaire would wash his clothes by hand because he didn't want to pay for them to be laundered. Something which as a non-billionaire, I get. Dry cleaning is a bitch of an expense. But as an oil tycoon? I am so not here for this.
Eventually, his button down shirts would become frayed around the cuffs, and rather than just buying new ones, he'd trim the frayed bits off.
