Went into a Morrisons and used the self-checkout, the assistant ran after me and said my card had been declined we went to security and showed them my receipt yet he still said I had to pay for the goods from the machine that I had not even used saying it was mine. I refused.
Also, I find their products have been going up regular in price and quality going down many fresh items going rotten after just 2 days, the self-service checkout staff are almost none existent and when the red light flashes they either just stand there or walk past ignoring you I have walked out so many times leaving my goods because staff don't attend. They also allow people to put children in the carts with dirty shoes after they have been standing in who knows what then the next person has to put their food in it, you tell the staff and they simply don't care its a health and safety issue and ignore you.
This is not just one store but different ones around the country.
Do I need Morrisons, No I have plenty of other stores to choose from and from now on I will never go in any Morissons again.
