[TheThinkTank] In-shop bike check/claim ticket?

We're in the midst of a nasty situation where a new visitor parked her bike in our Donated/To Be Assessed pile, then left it there for a week. It was a good bike, and it sold quickly. Fortunately we know the buyer, and we're probably going to get it all sorted out.

Does anyone use a bike check-in or claim ticket process to avoid this sort of thing? We've also had some issues with visitors either claiming a shop bike was theirs, or ownership of a visitor's bike coming into question (one visitor claiming another stole it). It seems like some way to check a bike in could help, but we don't want to add much drag to our shop process.

Any ideas?
