In the days of manual cash registers, if a customer claimed they were shorted in change it was much simpler for the cashier and the customer...no problem, no heated discussions. You simply "checked-out' the register, counted the money on the spot (if you were good this took about 3-5 minutes). If the drawer was "over" you gave the customer what you owed them and apologized; and if it wasn't, the customer shrugged, apologized for being mistaken, and went on their way. Now, with computerized registers, (and because everybody knows that computers don't make a mistake), you have fill out a bunch of forms, and come back to the store to see if it checked-out right (or the next day). And that's providing the cashier and store manager is honest about it...the days when you could ask for them to count it out right in front of you are gone. Of course, now, the customer is never right. I'd say that was a bit of techno-regression.
