I know I have ranted before about this but - people who stand far too close in queues (or anywhere else!) drive me mad!
Just out of Boots, where the row of self service machines is along by the front window. I happened to be at the first one, nearest to the entrance of the row.
I knew there was a couple right behind me ie far too close to me. The man was practically hanging over my shoulder. He certainly had a good gawp at what I was buying and actually had to take a step back to make space as I turned to leave.
Nobody could possibly even attempt to jump the queue because of the layout but in any case there's no need to stand on my heels, you fucking idiot.
