Terrible attitudes from manager and from waitress

I was Rodizio Fourways tonight, after having ordered 2 drinks. The waitress approached us for our next orders, we asked for desserts as out of preference that it was we felt like, she frowned at us and questioned why we didn't order meals. How disrespectful first of all to question why we wanted desserts, as customers, our preference is ours, not for you to question. And finally when the bill came, there was a charge for entertainment of R60, the waitress informed us that we should have been made aware at our entrance of the resturant but no one bothered to inform us, secondly we were placed at the back far away from the entertainment, in fact we didn't even see anything form of entertainment. Angered at the situation, we called the manager, the manager to our surprise was even more rude. He said he should have charged us R150 just for sitting on HIS SEATS. Totally disrespectful and misrepresented. Terrible exerpience!
