This game makes actually a lot of fun and gets somewhat addicting. Atleast I played several rounds to improve my highscore (EDIT: 132 seems to be the best I can get). I really like the sound feedback for crabbing a drink and happy/unhappy customers, it helps a lot to understand what's going on. If I remember correctly, there is no sound for pouring out a drink, so maybe add that. I really liked that you could regain lifes by cashing in - it's pretty risky since it needs so much time, but the reward often makes it worth it. Also as others pointed out, it can get a bit unfair, since sometimes you can barely fetch the correct drink before the customer is unhappy. Often I keep loosing all three lifes at once, since after the first unhappy customer, I have to pour out his drink, costing me enough time to loose the next two clients.
But overall a really fun little game, good job.
Oh, man, this is the best feedback I've gotten so far. It is really nice to hear the game has potential to be addictive just because the player wants to beat the highscore, I guess it could be even better if you could see other people scores.
I'll keep in mind that I have to balance the game more, I really appreciate your comment and also props to you on your score, the best one so far.
