Packet thrown back at me

I went to the zone last weekend to watch a movie.<br> I had one bite left of candyfloss in a packet that i was going to finish while I waited the 20 min before my movie started.<br> as i walked in the man at the ticket line said i cant enter with the candyfloss. I told him its a tiny bit, and i will sit on the couch and finish it before my movie starts. he said i am not allowed to sit on the couch and finish it. So i stood there and finished it, gave him the packet so he could see it was finished and as i turned around he threw the packet back at me and had a good laugh at my expense with the other employee that was standing there, speaking in an african language that was not english. I asked that a managed come sort him out and how dare he treat a customer like that and nothing was done about it. when i got into the movie there was a black couplke sitting in the seats next to me having a lekker picknick with food obviously not bought at ster kinekor. they were eating a packet of jumping jack popcorn and had a packet of simba crisps with them and cooldrinks in a can. no tell me, why do i get singled out (one of about 15 white people that were at the cinema that day) and no one else?
