Then spend the 20 minutes, or don't. Writing "the answer to your question exists" isn't a meaningful contribution.

are you mad at me suggesting that they didn't write it down because they thought it would take them too long to write?

At any rate they didn't just say the information exists, they also said it was basic pawn shop training, so I googled "pawn shop detect stolen goods" the top answer was from quora https://www.quora.com/How-do-pawnbrokers-verify-that-the-ite... and there was something from a blog of somebody called the blog nerd which is a little difficult reading because of all the SEO keyword optimization he seems to have done

https://www.pawnnerd.com/how-do-pawn-shops-track-stolen-item...

there seemed to be a reasonable number of other informative links.

oops, the pawn nerd not the blog nerd.
