The Wrong Supermarket For Super Hackers

(It is the early 1990s. It is my last week of work at the only department store in town and we are just rolling out the first UPC scanners in the store. This is new technology at the time and understandably sometimes things scanned wrong. After a third item rings up at the incorrect price:)

Customer: “You are making things ring up wrong on purpose just so you can pocket the extra money!”

Me: “Believe me, lady, if I knew how to hack the computer system here to change the prices I wouldn’t be working here!”
