Screw white people and their*shuffles deck, draws card*courtesy to cashiers and people

If I pay for it it is going home with me lol That is what I would say.

I’d tell the cashier I didn’t want those things. And take all the things I did want.

Wtf no way
Sounds like that person was trying to scam you hard.
It never happened to me but yeah sometimes it happened that there weren't enough dividers and the cashier got confused, luckily the person behind me never tried to scam me into paying for their stuff.

Lol obviously, it was super simple to get out of: "Nope, those aren't my items. Anything past (let's say bananas) isn't mine."

No, it's not racist because it makes fun of white people.
That's sarcasm from me, but a lot of people actually think that way.

Yeah but it implies that non-white people don't give a toss about cashiers.
But you're right, racism is racism no matter who it's directed at.
