I was rudely spoken to by a so called security supervisor Phumelele

I walked into Pic n Pay mahube mall in Mamelodi East at about 16:55 to get a few staff for my so who is going on a school trip. My self and my Kidz were busy picking up some items from the shelves. We walked into the juice section which by the way exit into the wine isle. I picked a bottle for my self and guy co e to me and tells me that the children are not allowed there. Firstly there's no sign because obviously its In a store and not a bottle store. I told him but him there's no sign that says no kids allowed on this particular isle he rudely said I went in with them via they are 18 when he could clearly see that they are younger than 12yrs. Iv never taken any of my 3 children to a bottle store so to be disrespected by someone who should have made his business to let me know before I went through that isle with my Children instead he waited for me to walk out of the alcohol isle only to tell me wat to do. I tried to reason with him and told him that he was bn rude he didn't care and didn't even apologize. Only to find out that he is a so called security supervisor.
