Think of a congressional hearing or even better McCarthy era hearings.
It will be twice as bad.
The board is clerked by a very sharp young attorney.
I was listening to a guy tell the board all about how he found a company that installed motorized window shades and the qualifier had died and he was "pulling permits" for them to help them out.
They politely listened, and then fined him $5000, suspended his license for a year and of course did not approve his application.
Know the rules, and choose your words very carefully.
