Y'know what I really hate about Subway? The decision tree. What kind of bread do you want? What size? What kind of sandwich? What kind of cheese? Now, please tell us individually each vegetable you want on your sandwich...

Aaarg! I want a sandwich, not a conversation *about* sandwiches. There is such a thing as decision fatigue, and needing to make fifteen different decisions before I can actually get my sandwich means fifteen more important decisions I can't make after lunch. I might as well just make my own darn sandwich.

Also, the paradox of choice. The more choices you have, the less likely you are to be happy with whatever choice you make.
