Stop treating your black and coloured clients like *******

Im so fed up of always having to write negative reviews about this shop Pick n Pay Somerset west, i visit the store literally daily, as I pop in before taking the bus home. i always keep my backpack on as i put the things i buy in it. whenever i get asked to take it off at the door to leave on the dirty floor outside, i decline as i dont see why me carrying a bag is a issue,unless im being profiled as a thieve, and what is so obvious,is that only people of colour are asked to leave their things outside, and i even pointed it out when a white lady came by with a big bag taking it in. and its not the first time service was given in this manner where the colour of a persons skin determines the level and quality of service, its really pathetic treating clients like *******
