Why do people do this !?

Like I really want to understand why people choose to leave unwanted groceries at the end of a register instead of either putting it back or hanging to the cashier to put aside?

I work in a supermarket and am constantly removing these stray items.

Is it anxiety? Not caring? What…. I need answers !
