i dont think ive ever scanned anything incorrectly. even if i did, it would have been a piece of fruit. in the case that anyone ever speaks to me about it in the future, i will just tell them “oh, oops” and then fix it. doesnt seem like much of a liability to me.

on the other hand, when i ring things through, you better believe i notice if a price is off, then i have them fix it if its higher than it should be and i say nothing if its lower. sounds like they are taking the liability as it were, which again i dont think is a serious factor.
