Poor customer service with no etiquette

I visited the Gorimas in hyoer by the sea. The staff was rude and condescending. Firstly half the items are not priced i enquired about the price of the cashew nuts the sales lady said i need to go to the till ppint and scan i adviced i wont do that as whar if i dont find the price right and dont want the item, why should i go through that lenghts and if i dont want the item it will be left at the till point that wouldn't be considerate of me. She then said she will scan for me then the audacity of going to her colleague and whispering about me i asked her if she speaking about me she insulted my intelligence and said no she discussing something else, i clearly heard her say she doesn't want to go scan . The nerve of her sadly its staff like her that don't value their jobs as if it was not for customers patronage she would not have a job as gorimas would not exist. I suggest that gorimas send their staff for customer service training. I been told to not bother as gorimas management doesn't pride themselves on service and don't respond to mails etc. Nevertheless i hope this doesn't fall on deaf ears.
