Bring your own coke

Just to let you all know that before you go a Emperors, Take you own drinks. I played at multiple tables, and of course loosing my money due to their ****. I asked John if I could have a coke. I was told that you have to buy in for R500 or more to get a drink. Not taking into account how much I played and lost already. Which is properly on his screen. Yet, the black guy next to me was not even playing got a drink. So now, do I also have a pay bribes to win? Do I have to be a friend or be black to get a cool drink? (I'm not asking for gold) Do you teach you staff to use common sense ?
