So I bought my shopping in Tesco...as you do....said thank you to the cashier when she gave me the receipt and my brain couldn't decide whether it wanted to say 'you're welcome' or 'no problem' so instead it shouted quite loudly to the cashier and the whole queue behind me ...
'YOU'RE THE PROBLEM'
I just stood there, with us all looking uncomfortable and not knowing what to say .... plus a few sniggers behind.
What is the worse thing you've said without meaning to ?????
