You never had the absolute bliss of discovering your missing 10mm in your pocket once you got home?

Just degrease what you're working on and wear long sleeve uniforms. I do both when I can, but I always wear long sleeves. Helps prevent some cuts and burns too. If you know you're going to be on the floor, get a creeper, they're relatively inexpensive and have the upside of making it significantly easier to skate around on the floor. Plus you pretty much don't get dirty.

I don't mind getting dirty, but if I can, its easier to take the like 5 minutes or less of prep to prevent getting myself dirty in the first place. This way I don't get customer interiors dirty, leave grease prints everywhere, and make it easier to clean my shop uniforms when they're dirty.
