Bad customer service

Pick n pay Fandale on Republican liquor store in Randburg, the guys in there are pure example of crab service, their attitude is so cold , is like they doing us favour for shopping in there , I am not sure if is because they sell alcohol they then turn to peecive us as some drunken individuals but they just rude on a extreme level, ilcuding their supervisor , who had the audacity of pointing me and say, am a problem customer who complians like some kind of woman. I couldn't believe, the store need to be reviewed , and should be closed if need be.
