Because logically I should give tips to every service worker I interact with that makes min wage. I'm obviously not going to do that. If I do tip some category of service workers, it's certainly not going to be the ones that eat/delay/spit in my food as a get back for not tipping them, and it's certainly not going to be the group that makes well above min wage (I. E waiters are the highest-paid min. wage staff).
> Explain the logic of not tipping people who make minimum wage?
It's more that they're regulated, the price of the delivered food is already high, and I'm not putting a premium on their labour above e.g. the folks who prepared the food.
It’s you that needs to explain the logic behind why these people need to be compulsorily tipped instead of receiving a reasonable base wage.
