When my rabbits hit the sale table the auctioneer (not the actual person doing the auctioneering) made a huge fuss about the rabbits water bowl being spilled and getting the rabbits feet and bellies wet by holding the offending bowl up and proclaiming "This is exactly why" and proceeded to slam my cage around knocking my stainless steel pan on to the concrete, The cage of 20 birds was proclaimed to be "All roosters!" 3 times before bidding started while it was mostly roosters there were some pullets but that was my fault for not separating them into more cages, I could have said something then but was kinda stunned and just watched in disbelief mostly,
I'm not that shy.
A long time ago at an auction a ring man announced my forced air Hova Bator with turner as a still air Little Giant. There is a world of difference between those two. Also failed to mention the almost new egg turner inside. I walked right up to the table and corrected him in front of everyone. Acted like he didn't know what a Hovabator was. "And an egg turner," I said. Think it ticked him off so he just said "And turner" but didn't show it. It sold for $42, so I POed. Probably would have let it go, but by then I was annoyed too.
Took it to another auction that sold it right and it went for $67.50.
So, I would add to Les's caveat. It's yours not only yours till the gavel falls. It's yours till you let it leave the table. You can always PO.
