Here is a conversation I recently had with a Spokane man selling a scary looking industrial fan on Craigslist. If you're confused about how these types of buyer-seller conversations should go, they should be succinct, to the point, and foster a win-win environment. This one checks all three boxes.
Seller: "I have for sale an industrial fan. This thing pushes a lot of air."
Buyer: "Can that fan shred a live badger? I have a big fan of my own, but it can only shred cats and possums, not badgers. Looking to upgrade."
