1 dont walk alone after 1am
2 stay near other people, yell out if needed, dont engage a fight
3 if you have to fight use a headlock. 2 guys tried to fight me, i put the first into a headlock and threw him into the 2nd guy, they both fell over. I got away. Dont try to punch or use muay thai unless you are very good. A headlock works best and they dont expect it. They expect a punch or kick.
