Was so mistreated

The situation goes like this…was on my way from work ,then I decided to pass by Cambridge store at Mayibuye Tembisa…so as I enter in their entrance there are securities there that search our bags,which I don’t have a problem about that …my bag was search and nothing was found then I go in(so there was a small juice the TROPIKA ,WHICH WAS SUPPOSE TO BE MY LUNCH BUT THEN SINCE I HAVE FORGOTTEN ABOUT IT, I COULD NOT DRINK IT ON LUNCH TIME AT WORK ,EVEN WHEN THE SECURITY WAS SERCHING MY BAG ,SHE DID NOT SPOT IT so nothing had reminded me that I had a juice)…so after I entered ,did my grocery shopping ,went to the till,pay the amount of R300 and something..then am now approaching the exit, they check my groceries in the plastic if its matching with the till slip and everything was fine ,so now am about to go out, there is another security at the door to search my bag again…she searched it deeper and deeper and underneath of everything there in the bag ,comes that juice I have already forgotten that I have it….and he calls this Guy …with a name that I have forgotten, but I can point him..but others nicknamed him Mkhulu…he is a Portuguese I think...when he came he accused me of taking the juice without paying for it since I had no slip for it…in other words its ****** from their shop..he said since I don’t own any proof that I did not ***** it …its either I pay for it or he is taking it…was so ****ed I don’t wanna lie..like really how can I go to the shop and buy for R300 and something then ***** something for R5 something…my character was deformed that day…when he made that small scene than am not goner leave with the juice blah blah …and he take it and throw it somewhere there next to where the others stand…I just left the shop angry and I nearly cried..thinking of how they have just mistreated me..after being their customer forever…
