You are nothing as clients

I went to Macro in Wonderboom junction on the 28/04/2016 –bought over R2500 , paid for it and on my way out , I was stopped as security , the women who stopped me –pushed the trolley back so hard that it banged into my groin area , she then started opening the bags and scanned things , I asked her what she was doing , when she almost screamed at me –she is doing spot checks , I told her that she good just have told me in a nice way , and proceeded to walk out –as I walked out I heard laughing , turned around and sow the same person pointing at me and laughing at me with the security staff standing with her , her name tag said Elisabeth Ntlatleng –I never felt so humiliated , is this how your client are treated if they want to be handled with respect ???and wont be going back ever
