For minor choices, I like the strategy (I may actually have heard it here) "flip a coin, see how you feel about the result, and act on that feeling".

Same. It is fun to see others' reactions to that. Because what to order at a restaurant is such a momentous decision that a coin flip is inappropriate? Nah, probably just that it is an odd thing to do. But the first time you take someone else through that exercise is great, as they realize they already knew what they wanted the answer to be.
