The LBS Peter Principal: By 2 pm, every tool in the shop will be in someone's pocket.
Then you have two choices: (1) if you can see the tool you want, lift it directly from the appropriate pocket (however, fishing expeditions are not allowed), or (2) declare loudly "We've reached the Peter Principal. Everyone empty your pockets." It used to really make some of the guys jump when I would lift a tool right out of their pockets. But no one ever lifted tools from my pockets.
Oil is good, grease is better.
