So what if I have a Mastercard and go to the Olympics?

So let me get this straight, Visa is the only card accepted at the Olympic games? I don't get it. What if I only have a mastercard and want to buy a hot dog? I can't? That is the most ridiculous thing I have ever heard. Even more ridiculous is Morgan Freeman's voice on the commercials. Shawshank Redemption was years ago and with his personal affairs no one should be thinking his voice is the voice of reasoning or storytelling. Who even watches the Winter Olympics anyway? If I wanted to see some Red Head on a snow mountain I would watch the x games. The worst is the sport the one where they push some thing down the ice and broom in front of it and get it to stop somewhere. I don't know what this is called but how is this even a sport and who wakes up and trains for this? Come on. Get real.
