Servio Garcia could have made a hell of a telemarketer. Or politician or con man or hostage-situation-breaker-upper. When he answers the phone at Bergamot, he broadcasts sincerity through the wires. It travels into your ear and warms you, leaving you flattered when you hang up, reservation written in black ink on a scrap of paper. “Hey, honey. I think that guy really wants us to come to dinner. I don’t think he’s putting it on.’’ His hospitality is convincing. When he says “We look forward to seeing you,’’ you believe it. When he says “Welcome,’’ you feel welcomed. As general manager, he’s using his powers of persuasion for good. You wind up well fed at the end of each transaction — not possessing an unwanted set of encyclopedias, vial of snake oil, or deed to a piece of land that does not exist.
