Boy, this wasn't thought out too well. Nothing more frustrating than a game that you can play perfectly cycling through drinks like a madman and still lose. True RNG gives rise to these situations, it would be better if it was weighted, similar to how Tetris uses a deck of pieces and only reshuffles the deck once you've been dealt one of each. Implementing the RNG as a deck of drinks would make much more sense. If you did do that, balance the deck better.
