One of the coolest things I have ever seen was when I was at a local bar one night and the server brought over a beer tower that was filled with beer. I asked her “what the heck it was” and she replied that it was indeed a tower of beer and that the bar used these for those times when many pitchers were being ordered. This way, the tower held roughly 3 liters of beer and the drinkers could serve themselves instead of bugging the server all the time. A very cool invention!
