Would you go back?

If it is my mistake, I return and pay. If it is their mistake, however, I consider it a freebie.

This is how I see it. I would feel horrible if I accidentally took something unpaid, but I feel elated when they goof and I get something free or cheap.

I personally don't see how someone could NOT go back and pay. It would lay on my concious for a long while. No matter how much the item costs, it does not belong to me unless I pay for it.
