Sure thing—think of a wink or a raised eyebrow as a secret handshake. When you lean in just a tad, people feel you’re on their side. A pause before you speak makes them hang on like it’s a cliffhanger. And hey, if you flash a grin that’s a bit too wide, you’re basically saying “yes, I’m here to help,” and they’ll line up faster than a popcorn line at a premiere. Just keep it natural, because nobody likes a rehearsed movie star.
