Checkers checks nothing

Today was a real shocker and the first time in a very very long time that I raise my voice about service standards at Checkers Linton s Corner. This is my third bad experience at this specific branch but ive now had enough. Firstly the cashier that served me (mapitsi mashabela) was snorting mucus ongoing, rubbing her nose (feel free to view CCTV footage) Then I requested twice for her to scan Super C s individually as its a promo running but I brought 2 x 4 packs and then a single to scan, asking her twice she still ignored me and proceeded. Then argued with me that it will be the same... and it was not so I waited and waited. I have to repeat myself 2 to 3 times in most of my communication. I've had 3 incidents at Checkers the grove as well and this was honestly the final straw ... and the worst ive even experienced. Im done with Checkers as I know and told the manager ... once I leave the store everything just carries on as normal. It was as if im doing the cashier a favor to shop at this branch. Im gone from Checkers and you will only see me there again if no other option or extreme emergencies
