I put my basket on the till, turned away to get a bag. Turned back, couldn't see my shopping basket – someone had put their basket ON my basket and were scanning their items. When I remonstrated with them, they said: 'What are you going to do about it?' Then ignored me. I swear, next time I'm going to pull the entitled tosser's bloody airpod out… What is going on?! I've never come across such dickish behaviour before.
