Morrisons review: Bad customer relations at self checkout at 11.30am

I was shopping today at morrisons barry vale of glam like I have done everyday I spend approx 500 in the store every month however today I was very upset with the service I received and I do not wish any other customer to go through the experience I received the manager I spoke with julie was unhelpful and the member of staff involved was rude and starting an argument with the customer myself I have been in customer service all my life and never experienced such a attitude as if she wanted to argue she did not diffuse the situation at all I am letting you no as I feel very let down with this store the manager before was excellent tony ware but know it seems to be going down hill.
