Be Ready To Fight In Your Mind and If He Shoves You I Beleive That You Have Every Right to Defend Yourself. If he is bigger than you and you think he may be a bit much to handle you should attack him but if he isn't too much stronger than you put him in some kind of hold. ( I like the Five Sec sleeper Thataway if he tries to resist you can just squeeze and he'll calm have to calm down.) The less you hurt him the better. Beating the pulp outta someone isn't worth paying for mouth reconstruction or any of other possibilities including death.
