There's no doubt McDonald's is a clever innovator, but whoever designed this cool soft drink lid dispenser is a genius:
Next to the drink dispenser is this neat little rack of lids stacked horizontally. When you pull down on the door, plastic claws on the inside of the door grab ONE drink lid that comes away from the stack neatly. All you do is lift it out of the top of the door and the spring-mounted door closes and grabs a lid for the next patron.
Simple and clever!
