I had just voted in today's local election.
"Wait!  You can't leave!" the poll worker said. 
I was puzzled.  I'd voted via touch screen in many previous elections, so I knew I hadn't made a mistake.  Why would I be detained?
"You need a Tootsie Roll," the monitor said, handing me a piece of candy.
"This must be the Christian charity I've heard about," I thought.  "During the 12 years I voted at City Hall, no one ever rewarded voters with sweets."
That was unexpected, but it was a considerate incentive for completing a civic responsibility.
