Automatic Bartender, 1956

This automatic bartender (the machine, not the woman) was designed to mix a drink in 3 seconds. Upside - you get your drink in 3 seconds. Downside - no bartender to listen to your drunken ramblings or dispense sage advice.

Although this one never caught on, people obviously think it's a good idea. A quick search on YouTube shows literally dozens of contemporary versions of this, ranging from the home made to the technically advanced. This is my favourite: http://www.youtube.com/watch?v=9IfJywRrcRw&feature=related
