Bruh. Not EVERY interaction with a cash register or payment portal is meant to include a tip. The bill is for the goods or service for which I am doing business with you company, i.e. the only reason you are getting my money in the first place. The tip is for the individual that performed a service to me beyond simply providing the previously mentioned good or service. And ideally it is for service beyond the bare minimum (but due to shitty minimum wage laws for roles that expect tips making them dependent on them, there still exists an expectation to tip even for mid or bad service). I will happily tip a server, bartender, barista, barber (there are a weird number of service jobs that start with 'bar'...), or someone that is interacting with customers, providing an experience of service, and will adapt to my shitty needs and requests as a customer, particularly if they are dependent on tips as a portion of their wage. But I am not tipping a cook for making my food in a restaurant. I am not tipping my mechanic for doing an oil change. I am not tipping a cashier for taking my money. I am not tipping MY FUCKING LANDLORD! You are already charging me for the things you are doing. I am not going to voluntarily inflate the price you are charging me for no damn reason. Fuck, sometimes it isn't even clear who would be getting the tip. I'm surprised they don't already ask for tips at the grocery store self-checkout. This shit is dumb.
