I think the correct play would have just been to let the drunk dudes get tired and give up. "if we don't go out to hang with them it'll be suspicious" no, what's suspicious is a couple of drunkards harassing other patrons. Why should you open your doors to them in the first place?
What sucks is when people do have something interesting to show or tell, they can't help but want to say it. But Kaiji, jesus you're fucking up, my dude.
