This is a true story in which joke week climbs from out of the grave to stumble forth again.
I was working on the automated check in machine and since we were in the general run up to closing I was pretty busy. One of my kind co-workers, walking by, saw a tangle of magazines coming through and so started to help out. She gathered them up and fed them carefully through, but the machine just spit them into the exception bin. There was no reason for the machine to be unable to process them, it just... didn't. Magazines are simply one of those item types that the machine has problems with.
My co-worker may have even tried one more time to get the magazines through, but whether she did or didn't, at some point, she turned to me, exasperated, and said "I don't know what it is, but I just can't get the magazines to go through!"
"Oh, don't worry about it." I said consolingly. "The magazines have issues."
