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.
I don’t know where you live, but start local. And in the meantime, stop going to restaurants.
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.
