Quecision
The feeling of trepidation upon deciding which queue to join at the supermarket/bank/post office. In accordance with Murphy's law, one always joins the wrong queue, only to watch other queues progress much more quickly than yours.
"I was at the supermarket and at one check-out was a woman with a massive trolley full of groceries and in the other, several people with smaller baskets. It was a very difficult quecision."
