When you sit to dine with a ruler, note well what is before you,
and put a knife to your throat if you are given to gluttony.
Do not crave his delicacies, for that food is deceptive. - The Book of Proverbs
In my experience rich people are very 'outcomes focused'. They almost always expect something in return. I always ask myself why are they giving food to me specifically and not just some random person?
That's a pretty sad way to live. I mean, I guess when I'm back home and the "rich" person in the room (I went from rural america to FAANG salary), I just want people to enjoy themselves and not think about price when we're at a nice restaurant. That's the "outcome" I want.
Back in the bay area, the rich people in the room never seem to want anything in return for their hospitality. At most they want to hire me, but there's no expectation there.
Your experience (or maybe incorrect thought) is not what I've seen.
How often do rich people randomly feed you and what is it they want in return?
