i don't drink anymore dude, so i don't hang out in bars. ( in my wilder/younger dyas, i used to like to arm wrestle dudes and try to knock the of the barstool to get their booze). once, a dude tried to fight me, so i grabbed him and lifted him off the ground. he didn't mess with me anymore after that. another time a dude popped me in the eye, so i hit him back in the stomach. he doubled over. i wanted to finish him off with an uppercut to the jaw, but he walked away after i punched him in the gut! i was never one for fighting. (the key is to just "look" big and strong.) that way. they just tend to leave you alone.
