Especially if you work on a concrete floor, chances are you have a "fatigue" mat in front of your workbench. I like this one - I believe it's the kind used in commercial kitchens so liquid can drain through the holes. Small parts and bits can drain through there, too. So, when I drop a teeny truss rod cover screw, it usually lands in one of the holes instead of shooting across the room as it bounces. I can retrieve it by simply lifting the mat.
