Can you believe that I got banned from a club last night?
What happened that caused you to get banned?
There was a fight and my head got hurt...
Well, sounds like the business did what it had to do.  If you were causing a fight then it'll scare aware customers, which is why they refused you service.
It's too harsh to kick me out, I was just there to get drunk.
You were just there to get drunk, but you clearly started issues that required you to be kicked out. Maybe drink a little bit less if you're starting fights when you're drunk?
