going to a foreign game tonight...could use help

[Jeebus]

supposedly this game located in a city in KY (anonymity you know) is pretty good especially on tuesdays and thursdays and is widely known, widely frequented, etc.. My uncle knows and works with the guy who runs the game, gave me his number and all that. But when I called today to make sure it was Kosher that I came out tonight and get some details he had left for the day. So now I am planning on going out and showing up with the "I'm a friend of..." and then telling him (if need be) who I am and my Uncle. Is this appropriate etiquette, or am I gonna get shot tonight?
