A recyclable alcohol democracy. Essentially, it's a self sustaining bar. To build one, all you need is a small amount of money to "loan" this bar. Then proceed to sell drinks for cost plus maybe twenty cents. (round numbers work well) Once all the alcohol is gone you should have slightly more money than what you started with. Naturally, you have to keep loaning it money until the bar is self sustainable. Don't charge for chasers, mixers, cups, straws or ice. This cost should come out of your profits. Under no circumstances can the residents of the house drink for free, this defeats the purpose. People will respect you and your house more if they know you're paying as well. Also a stronger sense of unity is formed, and you won't find shit smeared in the bathroom. One major advantage is that if you only have three dollars and can't afford to go buy a bottle or a six pack, you can still get three drinks. Likewise, if a girl, perhaps, doesn't have five dollars for a cup she can buy four drinks at The Co-Op. Reversely, if you have, say, twenty dollars you can buy twenty different drinks and not be stuck with that one bottle you would have otherwise purchased. Continue this until you have enough money to buy materials to actually build a bar, purchase a sound system and glasswear.
The Co-Op is a universal name for such a bar. It originated in Milwaukee, WI a few blocks south of the UWM campus in 2005. It's perfect for any size house, apartment, or flat and works for all entertaining purposes.
The Co-Op is an excellent place to go for cheap booze after the bars and liquor stores close
