I was inspired by the condiment taps during a recent visit to the King of Prussia Shake Shack. It is convenient to have the ketchup and mustard available to dispense with the pull of a lever. Soda and beer are almost always on tap. What if doughnut glazes were on tap? What if, (there probably already is), ranch dressing was on tap? I'm sure barbecue sauce is on tap. What about chocolate and caramel sauces? What if you could dress your own doughnuts?
