Forced to eat a buffet in 30 minutes & pay in full

Due to the load shedding Hatfields was experiencing on the evening of 07/02/15 we decided to go to Menlyn for dinner.Upon walking to the food court we were stopped by David who presented us the buffet special on offer at the Food chain at 19:25.Considering that there was no electricity we accepted to eat at the Food chain as there was no rush to go home.My frustration rose when David came to our table at 19:55 to tell us that they are clearing out the buffet and we should take whatever we need before they do so. On your website the trading hours are from 8:00 to 22H00.I must highlight that the reason people choose a buffet dinner is so that they can spend their time together and the hot food. I cannot believe that he failed to inform me and other guest that he is closing the buffet at 8pm.Despite talking food to our table when informed, the food got cold. The manager Joe didn't seem to care any less. When I went pay for my bill he and the manager requested cash from all the guests. I was not the only frustrated customer there that evening. I wonder if the staff is *****ing cash from Cameron, I have emailed Cameron the owner and haven't received a response as yet. I am very upset.
