HOW TO STOP FIGHTS FROM ESCALATING

There is a storm passing by, New Yorkers seem edgy on this one, even it hasn't approach yet. Went out with 2 fellas, to one of our good spot, "Franklin Park." The story goes like this...
  1. โ€ข
    We had 2 cups of pints each, with in the past 3 hours
  2. โ€ข
    DJ started playing good old classic music from 70s to 80s
  3. โ€ข
    Everyone started to dance
  4. โ€ข
    We started dancing too
  5. โ€ข
    Suddenly a guy passing by my friend, put his hand on my friend's back, then rubbed it slowly till it goes down onto his buttock
  6. โ€ข
    My friend reflexes kicked in as he moved away from his grip, my friend said to him;
    ๐Ÿ˜  "YO WHATS UP?!"
  7. โ€ข
    The guy snapped and said;
    ๐Ÿ˜ก "I did that so you can F***** move!"
  8. โ€ข
    My friend responded back;
    ๐Ÿ˜  "yo don't you ever grab me like that if you need to pass by say Excuse me or tap on my shoulder."
  9. โ€ข
    The guy, incomprehensible, got to my friend's face;
    ๐Ÿ˜ก "WHO DA F*** ARE YOU TALKING TO LIKE THAT? I M A GROWN MAN!!"
  10. โ€ข
    I, who was paying attention from the beginning intervened and gently moved him back
  11. โ€ข
    This guy seem fierce for no reason, illogical, and obviously molested my friend. To this guy, he thinks he is on the right to be mad.
  12. โ€ข
    He went around us, tapped on his buddies (2 others), made a scene by smashing his cup full of beer to the floor, which people around us scattered, now it looks like a fight is about to break out.
  13. โ€ข
    Thank goodness there was a bouncer around, who grabbed him, lift him up and walked him outside
  14. โ€ข
    Then his boys got into our face, pissed and confused, I elaborated;
    "Your mate grabbed on my mate in the wrong way, then my mate tried to tell him not to do it again, he snapped at my mate and hell broke loose!"
  15. โ€ข
    The 1st guy said to us,
    "But that's my brother, you don't insult him!"
  16. โ€ข
    I responded;
    "I understand he is family to you, but he is on the wrong and has anger issues. You don't molest people and think you can get away with it. I m hoping it was a mistake, but he should've apologies and moved on."
  17. โ€ข
    The 2nd guy replied;
    "I m sorry for my friend's behavior, he is drunk and had too much on his mind."
  18. โ€ข
    He pulled out his hands as a gesture to shake
  19. โ€ข
    Shaked his hand with appreciation ๐Ÿ‘, but the 1st guy was unhappy, pulled his pacifist friend away from us;
    "Why are you shaking hands, why are telling them he is wrong, wtf!"
  20. โ€ข
    Bouncer came to us, and told us to leave. So we left, no arguments, no need to explained ourselves, we just don't want to be in there any more.
  21. โ€ข
    Everyone, enjoy your labour day and be safe!
