I'll address the McDonald's one....

There's always those customers that just stand there and stare up at the menu, it's a deer in the headlights scenario. Too much to process to make a decision. My god man, beef like substance or what might have been a chicken, just pick?

Now if we could read their minds, and only show them the right couple of items we can direct their purchases, show the right addons, and make more money.

We all do that analytics now in our business, cause we're trained and knowledgeable, we ask the right questions to arrive at the best solution. If we could get at the data in a straight forward manner, without the dance of "he's just trying to sell us stuff we don't need", and how much they're going to spend, we'd make more money too.
