I can see where you were going with the idea and I like it a lot. But the game itself lacks a lot of polish.I had to read others' comments to learn how to play (you click on a drink and then click on the table to send a drink to the customer in the queue, for anyone wondering). And still, the controls didn't always work. Also, whenever new customers appear they can obscure the the need of the customer before the new one so you don't really know what to send.
I think it would be a fun experience if it were not for some inconvenient features.
