Race service from Spar Radiokop

Spar Radiokop Today I walked in at Spar Radiokop no security at the door so I started with my shopping halfway a security guard stops me saying in suppose to leave my bag at the door I said but the is no parcel counter and this is in front of my kids I said buy its not written anywhere that we leave parcels at the doors then he says he will throw me out and grabbed my bag from my son then had to follow him and the manager came and the was another customer who was white passing through with a bag he said nothing really it felt like a race issue since I'm black so spar Radiokop has a race service worsted customer service thinking that Im also I'm retail just disgusted me
