You Run a Large and Lucrative Bar and Restaurant, and You

You run a large and lucrative bar and restaurant, and you have just hired a new bouncer. You have explained to him that it is always best to be friendly and to calm angry patrons. Describe to him how far he can go to protect himself if attacked, and why he must learn to control himself when provoked. Explain also how his behaviour, if he assaults a patron, could affect you.
