Baynes Bakers

I am most annoyed. I went into this store this morning, which I will never go into again. To buy a morning roll for 30p, I had a £2 coin and a 50p coin, I handed over the £2 coin as I needed the 50p for something else. I was given the change of 50p when I queried it I was told that there were no £2 coins in the till and they flatly refused to believe me. It wasnt as if I had handed over a note. They will check at the end of the day to see if they are over I doubt it as they said there was no £2 coin in the till. Has it vanished into thin air? I have my own opinions on the matter. Please customers tell them what you are handing over to them and check your change. Last time I ever shop at their or at any Baynes shop.
