Always knew I had a screw loose

If anyone is at the St Louis airport- One of the micro screws in my laptop was loose from a recent unscrewing and fell out when i was there a couple days ago. would you be a lamb and pick it up for me? Just check the floor around the American Airlines Terminal. Its half the size of a fruit fly and blends in with the design on the carpet. shouldn’t be too hard to find. thx.
