So, I saw something here in India that can make you a bazillion dollars.
There's a bar in India that has a big electronic board with all the drinks and prices. And the prices of the drinks go up and down based on how many orders they get. If a certain beer starts selling a lot, the price goes up. And vice versa, drinks that aren't in as much demand, the price goes down. People will watch the board and order drinks when the price drops on something or try something because it seems be popular. I think it's genius but I could be really dumb. It's probably already been done here.
