The graphics are poor, the music choice is off-putting, and the animation is choppy. But you know what? It's damn /fun/. And isn't that what games are all about? Having fun? In fact, I was actually somewhat disappointed that the game was short. That's why I'm not trashing this submission. The idea behind it wasn't bad. It was original and intriguing. It just wasn't presented in a particularly interesting way.
Just my personal opinion: perhaps you should consider getting someone better to do the graphics; find a really neat jazz, hip-hop, or whatever song on the audio portal, and give the game more depth (for example: 10 glasses instead of 5, aiming for customers sitting closer or further down, stuff like that)
