Businesses can refuse to take fake bills, check 20s, 50s, 100s... but your average person has no protection against them... and none on the 1s, 5s, and in your case 10s that are fake at all because banks and businesses don't check those, just pass them right on along.
And it's the one who has it in hand when a business figures it out that gets the shaft. You turn that in you do NOT get another 10 in exchange, you just lose 10. Not the business that gave it to you, not the crook who made it, you the honest citizen.
And THAT is precisely why when folks realize they got a fake, and the business they got it from says "not us" then their only choice is to pawn it off on someone else... or take the hit. For many folks they just can't afford to burn money so they continue the cycle by passing it on. I'm SO thankful me and DH haven't been stung by that, but I've known folks who were. BIL turned one in, got the shaft... now some years later he got another and just passed it on down the line. Figure eventually a bank will get it and THEY can deal with it.
I understand the rules that mean if a pawn shop is caught with stolen goods the goods are taken... because they chose to receive them knowing they might be stolen (having a local business's name painted on the side should be a clue GRR) but in this case innocent bystanders who had NO idea are being punished... NOT cool at all.
