Pathetic and ****** service

It was the 30th of March 019 in the evening my friends and I entered the Food *****s Market at Pearls of Umhlanga, we were comming from dining out at the Village table.. We recieved pathetic service let me just say it better I personally received a super pathetic from a teller and the manager" Gerhard" the manager as he has addressed himself.. I was at the till point with no one behind me my friends were on the next till I turned to ask my friend to give me my goods to pay so we will be out same time the teller which was a tall indian guy said "please move so that my customers can pay" this was not the approach I have expected so I asked him is that how he renders his service he then repeated himself to tell me to move so his important customers will pay, when I turned around to look for his customers behind me there was no one except the trolley that had my goods as my friend had passed it to me..I then asked who am I if I am not the customer inside the shop he could not answer that however Gerhard limped and walked towards us and he asked " what are you doing to my staff?" Which triggered my anger bullets as I asked him if he is talking to me he said yes then I said I think you better ask your staff what transpired instead if attacking me..he then responded by saying "let me tell you this my dear the customer is not always right in my shop" I then asked him what he meant he repeated himself.. My question is did I receive this service from an Indian guy along with a white guy simply because I am a black woman who was in the white dominated area or this is how Gerhad the manager manages the store as he had guts to follow us out as well and stood on the door watching us leave and exchanging words? Not forgetting one of his customers even advised him not to say anything to us but because he owns the store he continued until he realised that my friend was capturing a video..he also tried to call the securities for us but failed. Is this how the service should be rendered?
