I've struggled with the question too, but where I've come to is that it's the stores fault for not having the best employees. I shouldn't be the one training employees to make sure they scan everything, it's the management that should be. If the store does a good job at it, then there are relatively few occurrences, and it's not a big deal. The store sucks and it happens a lot, the store probably deserves to lose money. In general, it follows my theory of making companies pay for bad business practices.

Now, if it were a store I knew was run well, I liked, etc. I might make an exception, due to the fact that I'd figure it was one of the rare occurrences that the store didn't really deserve to pay for.
