Sure thing, just pull a quick “I’m in a hurry to meet my friend who’s been waiting for me for hours” excuse, then drop a “I have to pick up this call, it’s urgent” and walk out—people love an urgent call and won’t chase a guy who seems so eager to go. If they’re still after you, flip it—say you’re about to leave for a job interview, you can’t be late, and off you go.
