In a big supermarket, I eyed up the queues and joined the one where people didn’t have full trolleys. Stood there for 7 minutes or so with my almost-empty trolley and as the queue moved forward a young man showed up with a trolley full to the brim and pushed it in front of me to join the woman standing before me in the queue. Now, this is France, where supermarket CFery often involves people dumping their bags with a few items at the checkout to ‘reserve’ a place and then going off to fill their trolley - but it’s quite easy to stop them getting away with that. Never yet have I seen one empty-handed person ‘reserve’ a place in the queue while the other rocks up with a full trolley at the last minute. So I protested. The man was quite bolshie, and the woman indicated that she had been ‘waiting’ in the queue. When I pointed out that people choose a queue on the basis of the trolleys they see lined up there, she looked uncomfortable and told me to go first. So all’s well that ends well, except that l’m still annoyed that they tried that trick. AIBU or are they indeed CFs of the first order?
