a bunch of immigrants? who says that? I've been going to arena for years and the people have always been friendly, professional, and helpful. I have never had any problems with purchasing their products. I agree, Grindstone can be convenient but if you want variety and a much better selection of beers, Arena liquor is definitely the place to go. And, you can fill up your tank while you're deciding on which beer to get! Maybe the workers were just responding to your obvious ignorance and close-mindedness that rubbed off when you noticed that they were "immigrants." And poor people skills? People at Grindstone understand you? Arena liquor definitely have the best selection of beer in Columbia, and the people who work there are friendly and helpful, as long as you act the same towards them.
