Serving nasty food

After a break away weekend me and my boyfriend decided to stop at steers at the ultra city on the N4 Middleburg West. after taking a bite of my burger I saw fungi growing on it. We went to the counter were the kitchen staff claimed it was burger sauce. Since when does burger sauce have green hair? We demanded a refund but got it with a big attitude. After that the kitchen worker kept giving us a nasty stare. I will never support Steers again. And I will encourage other people to do the same.
