Ethical question

[Northwoods]

At the flea this am, I compliment a fellow on all his tools and we struck up a friendly conversation.  I commented that he was quite a seller and asked if he was a buyer as well. It turned out that he was.
We struck a deal on two Craftsman vises and a set of four nice little gimlets for cash plus his choice of three ratchets from my misc. bucket.  Craftsman, Walden, Thorson, Armstrong, etc. 
When my back was turned, he reached in my pickup cab and took two Snap-on rats and picked a third from the bucket and told me he had made his choice.
Well, those Snap-on ratchets look as much like the others as the MGM lion looks like The Cat in the Hat.  I corrected him and he quickly made his choice from the bucket as we had initially agreed.  I asked him, "Are you sure those are the ones you want?" and he replied that they were.  I thanked him for the deal and quickly exited via pickup. 
My question: Did I have a responsibility to tell him that one of the three he chose--a 3/8" Williams--was completely trashed and was in the bucket by mistake?  I believe he chose it quickly because he was embarrassed at being caught.
I feel just a tiny bit uncomfortable about the whole experience even though he tried to pull a fast one on me. 
What say you?

  The issue with the Williams ratchet does not come even close in grievance to the "fast one" he pulled with the Snap-Ons.  A slip-up does not compare with intent to steal. I would let it go...unless you were interested in continuing a friendship with the guy.  If that were the case you would probably tell him about your mistake and offer him a different ratchet from the bucket.

He had the opportunity to try the ratchets.  Who knows?  Maybe he has a kit for it.

sounds iffy to me (him, that is).    i wouldn't feel guilty at HIS indiscretion.   

on the other hand, he's probably lucky he's not wearing a wrench in the kisser.

Hello, Northwoods. Like you, I would have felt some remorse about him grabbing a non-working ratchet. But that would have been quickly offset by his initial attempt to grab the Snap-on tools. What goes around, comes around!!

If I were a buyer, and the seller asked, "Are you sure those are the ones you want?", I would either look at them more closely or ask, "Why do you ask?"  On balance, the responsibility here lies with him.

If you want to make Abraham Lincoln look shady, and you see him again, and it's really bothering you, you can ask him, next time you see him, if he's OK with the selection he made last time.  And, if he says, "One of them was broken, darn it!" you can offer to exchange it for a working one from a selection YOU make from your bucket.  And then never talk to him again.

Bill, I think you nailed it.  I'll see him in a month or so, and I will have a ratchet in my back pocket.

I sure as hell would not feel bad, he tried to steel from you. He got what he deserved.

I reckon he doesn't need any help, he knows how to help himself.

Humber, that’s funny! He made his own karma. I wouldn’t worry about replacing the ratchet.
