I was paying for items at the till in New Look and in the queue behind me was a lady with another lady who was a wheelchair user. While I was paying they were called up to the till after me and I was blocking their way. As I was preoccupied at the till, I didn’t hear them say excuse me a couple of times. I apologised and moved out the way. The lady who was pushing the wheelchair then said to the other person “don’t worry I would’ve just taken her ankles out if she didn’t move” while glaring at me. If I hadn’t have been with my mother I would have said something but I didn’t want to cause a scene in front of her. AIBU to think this was bloody rude and unnecessary?
