"The robotic Barkeeper understands natural language and hence takes orders in exactly the same way as a normal bartender. It has a database of cocktail recipes, and will propose drinks to the customer at the beginning of the conversation. The user can then choose any cocktail by spoken commands, or create their own cocktail by choosing the ingredients. Then while it is making the drinks, it keeps the customers entertained by telling jokes. The Barkeeper has an extensive joke database, with additional specific jokes about each cocktail and each ingredient. When it serves the drink, it also explains to the customer exactly what the alcoholic content is.

Looks like Einstein and pours me drinks?! Shut up and take my money!
