I'm in the US so I tip people who rely on tips to make it by in this capitalist dystopia, like waitstaff. That's fucking it. Anyone else asking for a tip can get rekt.

Why is this even an issue? Are people actually tipping everyone now? Stop it! Don't let people manipulate you and keep your money.

The machines should tip the customer for doing job well. After all, it's him doing the work cashier typically does.

This is like when fast food places ask if you want to round your order up to the next dollar to donate to x cause.

Like, no, Taco Bell, I don't want to pay you so you can turn around and get credit (both in terms of laundering their image, and for tax purposes) for my donation.
