Since we're talking about checkout and this is the humor thread, I remember back in the late 70s checking out at a Giant chain supermarket in Baltimore. Halfway through ringing up my items and bagging them, the fancy-shmancy new bar code scanner gun ceased to work.
Shortly after I moved to the Chicago western suburbs (mid 1994,) I was out at something like 4:00 AM, and stopped at the Jewel grocery store that was less than a couple of miles away to pick up some staples. When I got to the checkout, the cashier started looking all over the items on the belt. "Where are the prices?"
"Huh? What? Are the scanners down?"
She points to a nearly hidden sign by the entrance that I did not see, asking customers to write prices on the items with a grease pencil, due to period end processing, all of the scanners were down/disabled. And I sort of lost my cool. Apparently, all of the regular overnight shoppers knew this, and I was new to the area.
"ARE YOU KIDDING ME? WHO ON EARTH IS STILL TAKING SYSTEMS DOWN FOR PERIOD END? Good god, I work in IT and if I disabled systems for period end, I'd get crucified." Now, for the edification of those who aren't familiar with the chain, there's an elevated stand near the checkouts for the managers and for customers to get pre-approved to write a check for the groceries when they get back to checkout. My voice was raised enough to clearly carry to the manager' stand. Yes, I was a complete <BEEEEEP>, left everything on the belt and walked out. I've been in a Jewel I think once since then, and that was only because someone else was driving.
On a related note, someone I went to high school with (she married a very good friend of mine,) worked at the local grocery store until the scanners were installed. Everybody preferentially went to her lane, knowing that it could be 2 to 3 times longer than any other queue, and you'd still get out faster. She was just that good at keying prices in to the register. She quit to do something else when "any 17 year old nymphmaniac can keep up." Her words, not mine.
