What about research?

Before the actual event David has a face-to-face or phone briefing with you, which is good fun in itself.
He asks questions that will make his presentation sound authentic while fitting in with what he knows works.
The important thing is the audience. What are their hot buttons? How can he bring them together to make them feel as one entity facing a cruel and unkind world?
Because David always looks for grumbles. Set a grumble into a humorous context and it becomes funny.
Does funny carry a message? Often the very contrast makes them think while making them laugh.
What do clients say about David's research?
