White person chosen over us, Stellenbosch 4u!!!

Last night we went into Spar abt 20min b4 closing & ordered a large Mexican pizza. From beginning Simon was not keen on assisting us. He said we'd have 2wait long coz he was busy with a big order & I said it's ok we'll wait & placed my order. A white guy came abt 5-10min after us & ordered. We went 2wait at the restaurant where the big order guy was asked to wait. Once they were done with the big order we made our way to Simon only to find he was starting with the white guy, yet I know 4a fact that he saw we were still in the shop. I said can I pls have a Mexican, I was here 1st! After we had waited 20min, he said sorry I didn't realize we were out of mince & he didn't show interest in assisting further. I said ok I'll have a beef one instead. He said we are out of large bases as he started making 2large & 2small ones for the guy. Fed up of excuses, we walked away & heard him shout I can make 2small ones whilst the people in background shouted LET THEM GO. I know 4a fact that guy ordered after me. Spoke the manager who said I can come 4a free pizza only 2MORO. Not sure why the white guy left with 2large & we with none. As a loyal customer of Die Boord Im extremely disappointed.
