I cannot fathom how no one else sees this. They're trading low-value customers for high-value customers. Sometimes this makes sense. I did it when I had a little PC repair business. Low-value customers were a PITA and didn't make me any money, not worth my time.
But maybe they're smarter than you and I? Lemmy tells me cheap fast food is a right, as if there's no other choice. If that's how people are thinking and acting, instead of shying away from fast food prices? Fuck 'em. Let them pay.
