I went to the dentist today and on my way out I was recruited for a marketing public opinion questioning in the same building one floor down. It paid 10 Euro, so I did it. And also: My opinion now counts!
On my way out I stepped into the elevator and met my dentist and five of his assistants. They looked at me with great confusion. "Hello" I said. "Where were you?" my dentist asked. "Opinion survey. It pays 10 Euro" My dentist nodded thoughtfully. "There you have it, I'd get more money downstairs than upstairs."
