The rudest cashier that has ever been hired by the company

Went to Steers in Primrose to buy breakfast. The cashier didn greet, no smile just a straight face as of I was disturbing her. So I let that one slide, I kept my cool, the I ordered the breakfast pitta and a rib burger. She rudely said that there's no rib burger, in my mind I thought she meant that it was discontinued, so I nicely ask why do they have it on the menu of it was not there. She responds " I told you mos that there's no party.. of which I didn understand how does steers run out of patty whereas their specialty are burgers. And then I ask the cashier to call someone who's going to be willing to assist me as clearly she was not willing. she refused by saying that she is working alone... I asked for her superior the she said, they're only gonna be in on Monday. I even went as far as asking if she was angry about something, she rudely responded that she was ok just that she had some pain below her breast... and I asked her why does she take it out on me and she gave me attitude and pulled a funny face on me.. I ended up leaving the restaurant empty handed.. I am really really ****ed and hungry right now, coz of she's sick she should be on sick leave and not give us **** service coz she excuses herself by saying she's sick. Her name tag was written Lindiwe, I don't even trust that!!
