That’s not how anything works. If you want change, you need to vote for it. You’re not going to change the entire economic structure of the whole restaurant industry by being a selfish asshole. You’re just punishing the people who handle your food and making life harder for everyone.
It definitely does not work in an environment where lazy aggressive apatheists will support a system they don’t like by claiming it can’t be changed.
I don’t know where you live, but start local. And in the meantime, stop going to restaurants.
