I bet it's these types of missions that Presidents really love. It's not the obvious stuff that is asked of (one of) the most powerful people in the world, like declaring war or making executive orders or living in the White house. It's the slightly quirkier stuff, like brokering a clear version of Coke. I bet Truman loved this. It's like working at a company doing the same thing everyday, but being most excited for this little side project you have going on.
