I was in the supermarket yesterday, put my shopping on the belt, by the time I'd finished loading it the cashier had started scanning. Got to the end and there was a loaf of bread, he asked if it was mine, I said no. The woman behind me said "she didn't put the divider up so I left it" and then as I left, i heard her say "I refused to do it on principle as she (me) hadn't done it for her." Is that really a thing? She wasn't in the queue when I unloaded.
