"What's an average check per guest, and how big's a typical table?" Type their numbers in. Then: "So if AITableFlow catches just a few of the reservation requests that slip through every week, that's "+ that number +" back — it pays for itself "+ the multiple +" times over. It captures the requests you're missing and hands them to your host — it doesn't replace your reservation system, it feeds it."
Then hand them the iPad and start the free trial.
