To be fair, OP was more specific than "not wanting to spend thousands of pennies for others’ alcohol consumption." The penny pincher also goes out of their way to be compensated, going against the social etiquette.

One can also remedy this by not spending time with people who do not on their own initiative recognize the inequity of the situation and help make it fair. In fact perhaps you can think of it as an excellent investment of one's money to ferret out the inconsiderate, in order to eliminate them from the friend circle.

Sometimes you go out, and your friends invite their friends, and you are no longer with your core friend circle. I would say it happened most nights in my 20s in a big city.
