I'm not gonna leave this hotel unless they call the police on me!
That's rude of you. Why won't you just leave quietly?
I want to prove to myself that I'm an independent man.
It's good you want to be independent and an adult, but this behavior is just annoying and going to cause you issues. Forcing someone to call the police on you because you want to prove a point is wasting everyone's time. You should just leave of your own volition to save everyone the hassle.
Nah, I think the police would enjoy it. Plus my friends think it's funny.
Whether your friends find it funny or not, you are likely to end up with charges pressed against you. You may even end up in jail because of this. If the hotel asked you to leave, you should listen and just cooperate with them to avoid legal troubles.
