Worse customer service

I have never experienced such RUDE customer service from food *****s like I did today! The person that was by the fish section was Lynette. I went there to get fish and on my arrival I met only 1 person there and she just looked at us and said nothing. It was only after I greeted her and asked if she was alone that she told me that she’s busy and that I should wait, I asked her to get someone to assist and she said her colleague is getting stock and then looked away. After a few mins of standing there I asked her to give us just 1 fish so we could go as she was scaling a fish . She said that we have only been waiting for 4 mins so we must wait until she’s done! We patiently waited until it became unbearable to wait for her! I asked her to get someone to assist and she just looked away until I saw another worker who told me that they work according to sections and she knows nothing about the fish section. Then a lady came and said she was the HR and she got us a person to assist us . When he came ( Pat) to assist us Lynette told him that we are complaining cz we are waiting for her to finish!

I honestly need someone to let it make sense why I was not taken seriously as a customer as I was there only client there at the time and why I had to initiate a conversation with Lynette when she just looked at me and said nothing! What happened to customer service and making sure that the client leaves the shop satisfied?

I want Lynette to realise that at the end of the day We as customers contribute to her salary in a way . We deserve fair treatment and not judgements as her behaviour was made worse by the fact that my partner is a foreign national. She must stop her behaviour towards customers!
