Ster Kinekor need to do better

I wanted to take my child for a movie today as I already postponed and didn't wanted to dissapoint him again. I went on Ster Kinekors website to check the time and prices , I even took cash with in case the card machine doesn't work and we were set to go. When we arrived at the cinema,I discovered they now use self service. I explained to the assistant that I wasn't aware that they no longer accept cash and no where on their website they mention that. I proceeded to ask her if there's any way she can assist me as I'm now desperate because boy started crying. She told me no but I can look for someone in the mall that can pay so long then I can exchange the cash. I understand that she only do her job but had they advertised somewhere that they no longer accept cash I would've known.
