Isn't the price the point? The question is whether the poorer of the two is comfortable with the expense. At many times in my life, I was the one "not hungry" when invited to a restaurant.

Fine, xapata! Yes, if you suddenly find yourself with a shitload of money, and you have friends who can't pay their bills every month, they have $0.00 in the bank, literally can't afford to ever eat out, and a $20 meal would be a grand expense and a momentous occasion for them... yes, go ahead and offer to pay for those friends every time.

Thanks, I'm glad to have your approval.

If you're curious how I handle those friendships: I invite them to dinner at my house. Much as discussed in the article.
