I used to work with a guy who had 2 PH.Ds, in Computer Science and Electrical Engineering and over 600 patents but I kid you not the guy could not use the coffee machine. Now it's not like this coffee machine was as easy as a Keurig, it was some $20,000 espresso machine that took a while to figure out but I tried teaching him how to use it a few dozen times and still he couldn't get it right. It got to the point where I thought he was faking it so that others would make it for him so I offered him $500 if he could figure it out. Still nope. So for the remaining 2 years we worked together I made him coffee whenever he wanted, 2-4 times a day, and he bought me lunch everyday. Before I left the company I bought him a Keurig so that when I left he'd still have coffee.
