OK so I was shopping at Lidl and had a small trolley full of groceries. There were only 3 checkouts open so we all had to queue. The woman behind me asked if she could go ahead of me as she only had a couple of things. I asked her if there was any particular reason and she said no so I pointed out I had to queue too and she backed down.
It felt as if she was saying her time was more important than mine. She had no special reason eg had to catch a train so why should I let her go ahead and queue jump me?
