Unless your running a McDojo, there is no reason to not just answer the questions.
Most people will be calling just to find the location, hours and cost. They want to go to either the closest, most convenient or cheapest place. Nothing else will mean anything to them.
Just answer the questions straight up and offer them a chance to come watch or take a class and they can see for themselves if this is what they want to do. One class can answer dozens of questions.
