Aggressive Manager or owner

Andries at Aan de Doorns guesthouse falsely accused my son of stealing a Microwave...threatening him with the Police and throwing him out at nighttime! My son took it to the Cellar where he work and which he thought it belong to. He is unreasonable, aggressive and don't know the first thing of the hospitality industry...to be polite, reasonable and calm. You DO NOT treat anyone in that matter!
