Hahaha ! My dad did mostly the same thing with his home builder. Except he went to their exhibition stand at some local event. He just stood calmly there, talking with every potential customer coming in to share his story with the company in front of the boss, who was in the stand. They tried to get the security to take him out but since he paid to enter, that he was calm and stayed nice, they did nothing. Eventually, he got what he wanted to get : some 30k€ of construction work that weren’t estimated up front and that they tried to make him pay once back to the wall. And as a plus, the company’s boss took directly the management of the project.
