Supermarket responds after Reddit user’s warning about self-checkout overcharge — ‘Was annoyed that the total amount due on my supermarket purchase did not equate to the individual items I purchased.’::‘Was annoyed that the amount due on my Woolies purchase did not equate to the individual items I purchased.’
Not in software. The software is doing exactly what it was programmed to do.
So no software has ever glitched before and output a wrong result? What world do you live in?

If there’re two different items calculations one “real” one and “display” that’s an intentional choice made because they know there can be discrepancies.

Can’t be just an oversight. This has to be an intentional design decision. The “simple” (and economical) way to build this system is to build it so that the scan reads the price from a database and that price is then displayed and used to sum the total.
Keeping two prices, a display and a real one, is a design decision that adds a complexity to the system, makes it more difficult to administer and is an intentional design decision, especially if the numbers are allowed to differ.
A coupon not being applied correctly could be a mistake with that coupon. A sale not being taken into account, a problem with that sale or that UPC entry in the database. Those could be issues with data entry and data management.
This is different. This is intentional. And I’d bet, we’ve just found someone either cheating the tax man or embezzling funds.
Yep rounding errors occur, manual changes need to be inputted sometimes, display errors, sales mistakes. Nothing weird about that. In fact their policy probably has specific points to deal with discrepancies between list, scanned and total prices.
