More fun is better than more fast

Which would be more fun in an office breakroom?

o  A vending machine that dispenses snacks for free: no coins needed.

o A tray of free snacks.

Which is faster?

Picking an item and waiting for it to fall takes longer than grabbing something from a tray, but  joy, delight and fun are better than faster.

Note 1: The error message in the center of the vintage dashboard, "Your selection is sold out if knob will not operate," allows the user to fail, instead of preventing that. We can do better than that now.

Note 2: Using radio buttons as a secondary level of navigation for gum choices is a nice touch. Why not extend it all the way across?
