So I'm going round Tesco yesterday worrying about racism and political correctness, when I grab two loaves of bread and put them in my trolley.
I notice that someone's put a bag of sultanas in my trolley, and go to take them out. Then I realise that someone's also put some tinned food and a bottle of Bailey's on my trolley. Also someone has stolen my carrier bags.
Then I realise that this isn't my trolley, and can't decide whether to start all over again or what. Then I enlist the help of two assistants and spend ten minutes going up and down the aisles trying to find it. Eventually find the trolley, and after a brief exchange, we swap our shopping and all is well. She seemed totally unfazed by this, and I'll never know if I took hers or she took mine.
