Last time we went to the movies they were handing out empty popcorn bags. You could just go to the snack bar and get a free popcorn.
I started telling my (very smart) wife, "What a great word of mouth promotion. Everyone will tell their friends that this is the theater that has free popcorn nights!"
But as we stood in the 10-deep lines to get our free popcorn, she said, "It’s not about word of mouth. It’s a fantastic way to sell $4 sodas."
