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.
