Legally, you CAN’T make the employee pay for it! (I know people do that, but it’s still illegal) But beyond that: I don’t quite understand the mistake…If the order has extra, unordered, unpaid for stuff included in it, you have to decide how that happened. Was it deliberate - that’s just theft, and the only solution is fire that employee. If it’s accidental, then try to figure out how to fix it: Does someone write orders in a confusing, illegible fashion? On POS generated orders, the same questions. Can you make the font bigger, better? Or is the problem that someone just doesn’t pay attention? Not all people are cut out to be in a reading orders, assembling orders position.
