TL:DR at the bottom

Background:

Last night went to a latin dance class. There I meet two cool chicks . After the class I went clubbing with both and made out a lot with the chick I liked. (Just a tip: To make sure the friend doesn't cockblock you, befriend her.)

Body:

So, after a lot of make out, dancing, fun, and lots of shit test passed. I see a creep watching us, staring, all the time.

He was drunk, completly drunk. And I usually stare back until they are scared away. But this guy was really drunk and socially inhibited because of alcohol, so eventually he came.

He did the ussual beta stuff, getting into the girls frame, getting creeply close. He was really anoying, and I tried to talk him into leaving, but the guy was too drunk and my chick was getting uncomfortable. And I realised that I had to take action, fast.

So I wasn't gonna hit him or anything. I just lead the guy to take shots with me, but I manage to not take the shots and leave him there(good), and I came back with my chick and her friend.

After more dancing and make out, I go to the bathroom. I come back and the creep is there. Girls are creeped and I'm starting to get pissed off.

The guy eventually goes away . I go to talk with the bartender and manager so they know that the guy was annoying the girls. And then the guy came back. It's over, now I'm pissed off. I find the manager to kick him. Then guy says he's really sorry and blablabla, and we let him stay leave us alone.

He never came back to talk to the girls and the girl were thanking me. The night was fun and got her number. She might become a plate if she plays her cards right.

Question:

I protected the girls and they know it, she was grateful. Things ended well. No fights or anything.

How do I make the guy go away in the first time or faster?

Ignoring doesn't really help, since he was really drunk and persistant.

I could have drag him out or do real harm to that guy, but:

a)Not gonna lose my reputation on that club (They are all my friends).

b)Not gonna risk legal problems and injuries unless needed.

The way I solved it is by getting the manager, which he's also the bouncer, and telling the guy to stop bothering or we will kick him out. It worked but I feel that I could have done something faster, and I needed real patience to not knock him out, because he was really annoying.

Any tips for solving these kinds of problems?

TL:DR Creep bothered my chick and her friend. Made him go away with the help of the bouncer after he came to annoy a couple times. Any tips for dealing with those drunk betas, faster or more effective?
