FIFO In-tray

So you have an In-tray on your desk or in your cubicle. You invite your fellow office-mates to simply put things in the tray if it needs to be done, and you'll get to it. But this system is terribly flawed! If you don't get through the whole stack before more things are added, whatever is on the bottom will be left unattended to (potentially forever or until you're fired, whichever comes first). Enter the FIFO In-tray! Things to be done are put in wallets made of card (slightly bigger than A3 and folded in half around the work-to-be-done) and placed at the top of the tray, with the spine facing the front of the tray. A button is located at the front of the tray which, when pressed, causes rubber wheels to dispense the wallet from the BOTTOM of the stack of work-to-do. The tray has walls to hold the stack in an orderly way, with a slot at the bottom for the next wallet to be dispensed through. The type of card is chosen so that two wallets will slide on each other and not stick, which would cause two to be dispensed at once.
