Humiliated

Ive been shopping there for 23 years. Me and my collegue Lindiwe went there after work, walking pass security thats always standing at the door. There were 2 employees of shoprite standing there, 1 wearing a "welcome" banner. We looked at them, all the while me having my jacket in my arm and my back pack on my back. We went or seperate ways, me getting a small trolley in front of the 2 men mentioned before. Putting my jacket into the red basket. I do my shopping, like always. At 16:44 I paid at Tseleng Mokoena. I declined a bag and took off my back pack which only had my empty lunch box in, standing there reararring it to fit in my shopping. The same man with the banner comes and tells me to open my bag he wants to see what is in it. All the people turn around and look at me. I am humiliated and irritated and rip open my bag and show him the lunch box, 2l coke, 2kit kats that was aleady in there, the back bag is open and empty and the bread is still lying there next to it. He just leaves. The cashier told me to remember my jacket and I said Im angry, Im not a tsotsi, Ive been shopping for 23 years. I walked up to the man with his "welcome" banner on who is now pushing trolleys through the door and I asked him if he is satisfied now, Im not a tsotsi and Ive bedn shopping there 23 years. If Im not allowed to go in with my back pack why was I never asked to leave it somewhere after walking pass them with it on my back as I always do. Why was I not watched on the security cameras if I was a suspected ********? Why was I humiliated like that?
