Second Story/Joe's Corner the worst

My friend and I met up for lunch at second story previously known as Joe's corner. It was our first time there. Our waitress was Theron. When we arrived there was a bottle of water with glasses on the table of which I poured half a glass. When it was time to pay the bill the waitress informed us that the bottle was R60.00 even though I only had half a glass and didn't know that the water wasn't free of charge. Also I raised that there isn't a sign that the water is not for free hence, this may be a way to trap customers into paying. Also no waitress informed us that the water isn't free of charge
