This is just silly nonsense I know.
Tesco delivery came this morning and as I was putting it away I noticed the pack of Mr Kipling cakes expired yesterday. I am 100% sure they are fine and that DH will still eat them.
Would you email Tesco to complain? I might get extra cake in next weeks delivery :)
YABU - Don't complain and eat your cake
YANBU - Do complain and have more cake
