@maxleibman I know it's meant to be a metaphor, but every obtusely wealthy person I've ever known in my entire life, I have no doubt absolutely would (and does) take the money from the leave-a-penny dish.
Years ago I worked for one such nincompoop, who organized a staff train trip to Niagara Falls. On the way back we had tickets to the central station, but the stop before was my usual home stop. As I got my things together to get off there, the owner caught wind, and loudly announced that he expected me to request a refund for that portion of my ticket. I didn't.
I also worked in accounting, so I got to see that the gratuity he left on the $2,000-ish bill for the team's dinner was a big fat goose egg - he didn't leave it blank, he wrote in the zero.
