I agree that you may have dodged a bullet- something sounds fishy here to me.
When I was working as a vet tech, we would occasionally be doing a PPE and the buyer would ask the vet about suitability (for the rider, for the desired competition level, etc). My boss generally did not answer these questions if the answer wasn’t positive, so as not to alienate the seller or give advice outside of his scope. However- he would often punt these questions to me, ie “I can’t say but my tech has a lot of experience in this discipline, so maybe she can give you her opinion” and then I could tactfully answer (hopefully privately, back at the truck while getting supplies or something) and his conscience was clear.
