Watched him last night for, I think, the first time and his unpretentious delivery, energy, organization, and straight-forward explanation were refreshing.
@Smurof is just making a funny observation - albeit using quotes might've clarified that......I don't think it was a 'dis' or negative review.....irony and sarcasm: things this board could understand better!
Ex-military could be a positive. Pre-meet negotiation and vibe should be the deciding factors. Don't overcommunicate, though, and don't sound suspicious. Meet in a public place, if he agrees. And all the other usual stuff!!
Tell him you're an honest person and will pay the full amount at the end of the meet. Show him the money at the beginning if you must, but ask him to agree to money at end and no money talk during. If no go, don't do it.
