Harassment Dely Road Spar Pretoria

I went to Dely Road Spar on the 29th of October. Just before I went to Tops and the pharmacy in the centre. When I entered with my trolley and shopping bags a black manager (I assume) stopped me. He lifted my bag with the purchased goods from Tops and the medicine out of the trolley, started shaking it and shouted 'what is this' several times, and in front of other customers. I told him it was goods purchased from the other stores and the slips are also in the bag. He kept shouting and shaking and looking in the bag and slapped on my empty shopping bags. This was harassment and ************, and he was very arrogant. I have supported this Spar for years, and this was the first time it happened. I went to the manager in charge ( an Indian lady) and she just pulled up her shoulders and said that was standard practise, no apology offered. Later I phonef to get the owners number and she refused and put down the phone in my ear. I won't be shopping at Spar in the near future and all my family and friends will know about this incident.
