This is an insane take. If you can't afford to work there for the wage, get a different job. If you can't afford to pay them charge more. If you can't charge more, don't run a food business.
If you’re the customer choosing where to go, you are choosing the type of compensation you’re supporting. If you don’t want to tip, stick to counter serve and pizza joints.
If I'm the customer choosing where to go, I'm gonna choose based on what I want. I don't give a crap how you compensate the workers unless it affects the product I get. That's not my job. My job is to have preferences and pay for them.
Now if you just have caring about workers supercharged as some part of your identity, then it should be part of your preferences I guess. It's not part of mine, and nobody will impose it upon me.
So I will stick to the best products. The market will fix compensation. If the product gets worse because people aren't compensated enough to do a good enough job, then I'll stop going to that place. And that place will either wither and die or that place will raise compensation to get the requisite talent.
I would argue anyone doing anything otherwise is kind of interfering with the markets ability to operate.
