McDonald's does not hire me to be their security guard and I am almost certain that they would prefer customers not doing ANYTHING other than be a good witness in the event of a robbery. I am in the fast food restaurant business and the loss of a couple of hundred bucks is much better than the store being closed for God knows how long so the dirt bag's remains can be removed and the restaurant cleaned up. Major chains such as McDonald's typically do regular cash pulls and the money is dropped into a time-delayed safe or a safe that only Brink's has keys to. Their exposure is usually pretty low.

Now if the dirt bag walks in and starts shooting up the place, I would certainly try and shoot him since he has gone from robbery to assault with a deadly weapon.
