Every mechanic I've seen work in any industry will do the same thing when he drops a tool or small part. He hops and jerks both feet from under himself and lands a half-step back, watching the object with laser focus as it hits the floor and jets off into never-never land at lightspeed. Reason for the reflex? When you drop something from a standing position it will always hit exactly on the toe of your boot and jet under and to the most impossible to reach spot of the floor under theworkbench, toolbox, or vehicle. If you jerk both feet back before it hits them there's a better chance of seeing where the thing goes. That of course downplays the statistical average that a special nut, freshly cleaned and dosed with threadlocker, will take the 30⁰ trajectory window under the workbench into a pile of metal dust and cobwebs 98% more often than it will go the other 330⁰ and settle on the clean, painted floor.
