Stop in for a cup of coffee

Take a picture,and then txt it to the borrower when you expect it back. I dont typically loan tools.
One young fellow failed to return as promised and that was it for me. He got a blast and banned from my shop.
I had some "friends" who would borrow tools, so I put the tools that I would loan out all together, in on box, area. When ever they wanted to borrow a tool, sure you know where they are. Till they were gone, then, sure you know where they are, nothing there, o well.......
