Many thanks to @liamdutton, a grammar-wise BBC weatherman, for spotting this goof while ogling the candy at the UK grocery chain Tesco.
Where does Tesco go wrong? It mixes up the homophones your and you're.
- You're is a contraction meaning you are. You're the one who wanted to see this movie. He didn't even notice that you're not wearing any shoes.
- Your is a possessive pronoun. I don't like your shirt. You'd better hang on to your money.
Correction: Smile, you're on camera
