The power of yes

You're sipping a coffee at an outdoor cafe in the center of town when suddenly a voice speaks inside your head. “Hello. We grant you this power: ask anyone any question, and they will answer 'yes.' If it's a request, they'll comply and will believe it was their choice all along. If it's a matter of fact, reality will shift to make what they say true. Use this power wisely. Or, if you prefer, use it totally irresponsibly. We don't care. We just want to see what happens.”
