10. I was at a BOQ/Convention dining area on surf and turf day...

Out by the ocean. The guy sitting alone on his side of the large table next to us set down his plate with T-bone smack in the middle of it down, then realized he left his drink inside and got up to go get it.
Three steps, and a seagull who had been patiently waiting on the overhang near the door was airborne and snatched that steak whole - got it halfway across the patio dining area before even the other seagulls figured out what it had done.

That was a loud and merry chase that ended about 100 feet away on the break wall area...
