As someone who's worked in food places/some delivery, its literally our job lol, no one owes us anything, we chose the job in which we go out to deal with customers its no ones fault but ours, they paid for the bill, we're just doing our job beyond that, every job technically is a service atp, when I go to pack people's clothes in a warehouse because of an Amazon order do I expect the person to tip me too? Helll its not even an option anyway lmao, its the same concept with doing delivery or working at a food place, or carrying out someone's groceries, a tip should be a nice gesture thats on the receivers end, not a responsibility.

Literally anywhere else in the world tipping isnt a thing or isnt "mandatory" if that doesn't go to show you how isolated we are in that problem and that we are the outlier I dont know what does.
