Depends, but a better (though still flawed) analogy is this: before dinner, everyone agreed and knew that if someone brought twice as much cash in their wallet to dinner, that person would pay more than everyone else but also get the best dish, the best view, and a massage while waiting for food to come out. And everyone had a chance to opt out of going to dinner before heading out, or to choose to not get all the perks.

Given that, it's sort of ridiculous for Fred to complain after dinner that he has to pay more than everyone else, and then to try to guilt trip them into paying an equal amount as him.
