Alright, so today I was ringing people up at the grocery store I work at, and despite it being 9am on a Saturday, things were getting busy thanks to a Badger game at 11.
An older gentleman, who quite frankly appeared to be fading mentally, came up with his groceries. I went through all of the standard practice, rang him up, applied his coupon, scanned his rewards card, but he needed help running his card.
Okay, fine, many people just seize up when they have to use a computer, much like how I am with heavy mechinery or fire. So the older gentlemen had another guy of about the same age with him, and he walked the man through running his credit card. The system was being very slow, as always, so he leaned over the counter while he waited and I finished up bagging.
Then the receipt printed and I realized he had his arm on top of the slot where the receipt prints from. I asked him to move so I could get the receipt. He then realized he was blocking it, and moved over enough that I could get out the receipt, which turned out to have the second half pretty mangled from a minor paper jam, caused by his arm being in the way.
I offered to print a new one, and he accepted, leaning right back over the slot. I told the receipt to print and tried to direct him to move his arm so he wouldn't get the receipt jammed again, but he didn't understand until the receipt printed and got jammed.
He barely moved over enough for me to get the receipt out, which was destroyed. The moment I closed the printer again, he started leaning in the exact same spot, except this time he also leaned on the button the feeds paper, so a whole bunch of receipt paper jammed.
I got it unjammed and he asked if he got his "10 credit."
I was a bit confused, because his coupon automatically subtracted $10 from his bill, but he might have been talking about our fuel savings program, which gives customers a certain number of cents off the per-gallon price of gas, so he could have meant that he should have 10 cents fuel perks by "credit".
So I printed another receipt, which he jammed again in the exact same way, despite my telling him to clear the printer. Finally, the other gentlemen with him who had helped with the credit card told him to move over, and we salvaged this last receipt, which, fortunately, was only crumpled and not ripped.
So that was the end, right? I wouldn't be asking this question if it was, so of course more happened.
I moved on to the next customer, started ringing her up, then noticed that the gentlemen who had jammed the printer 4 times and needed help following simple on-screen instructions never even grabbed his groceries and was heading out the door. I abandoned my station because there was no chance I could get someone else to run after him before he entered our large, busy parking lot where its almost impossible to find someone.
I ran over, groceries in hand, catching him at the door. He took his groceries, mumbled a obligatory thank you, not even realizing that he nearly spent a hundred dollars at the grocery without even taking any groceries out of the store, let alone bringing them home, plus I had just spent ten minutes reprinting his receipts and unjamming the printer multiple times, because he lacked the awareness to realize that he was jamming the printer.
