I mean, it's his drugstore, and here's Riff telling him he's not and ordering him to leave while they have the war council. I would've said "you either find somewhere else to have this council or I'm calling the police."
I love you, Kristen Stewart. :) You are so beautiful and talented. I would love to perform with you.
So he Just lets them run his shop when it's his store and time to close up? I mean, he asked very nicely "boys, couldn't you talk this somewhere else?" And Riff orders the owner of the shop himself to kick it. I'dve said "get out before I call Officer Krupke and Lt. Schrank."

As I said, he tries to get them to talk about it tomorrow but when Riff tells him sternly, he figures, "Okay, it won't be long." He does sort of put them down about their fighting (the stage version does more with it because the Cool number is originally there), but he figures that as long as they aren't doing anything terrible in his store, and they are regulars, it isn't worth the effort to throw them out then or call the cops (not necessarily Schrank and Krupke). When Anita is almost raped in the store later, then he flips out.
I think that Doc was trying to talk their differences out instead of rumbling. Doc also sort of flips out when he realizes that Tony's in love with Sharkleader Bernardo's younger sister, Maria, which is partly why Tony had made the rumble a fair fight. The conversation between Doc and Tony goes like this:
Tony: Buenos noches.
Doc: "Buenos noches! So that's why you made it a fair fight.. Tony, things aren't tough enough?
Tony: "Tough, Doc?" I'm in love!"
Doc: And you're not frightened?"
Tony; Should I be? (after which, Tony exits Doc's store.{
Doc (talking sort of to himself)" No....I'm frightened enough for the both of you."
While it's true that Doc flips out when the Jets are about to rape Anita, but Doc also flips out, after coming to the basement where Tony's been hiding from Chino, with Tony's get-away money, and he discovers that Tony still doesn't get the fact that it's a pipe-dream...the romance between Tony and Maria is never going to work out. The conversation goes like this:
Tony: Doc! You got it. You're the best pal I ever had. I'll pay you back as soon as I can."
Doc: No..forget that.
Tony: You know what we're going to do in the country, Maria and me? We're going to have lots and lots of kids, and we'll name them all after you, even the girls. That way, when you come to visit...."
Doc: (slaps Tony, hard.) Wake up!!! Is the only way to get through to you? Do just what you all do....bust, like a hot water pipe?
At that point with Tony (when he slapped him) he was still angry over what happened upstairs, what Anita said about Maria, and all the other stuff that had happened that night, he just snapped there. He was saying that the only way to get through to people is by hitting them, really? Acting tough and fighting and killing? He just took it out on Tony because Tony was there at the time.
Well, he gets business from them, since he knows them and he figures okay it is closing time but this won't last long. It isn't worth it for him to throw them out at that point. He does that later when they try to rape Anita, though.
Because the old man knew they were just kids...Punks. He was their age once, but those times were far different. Doc was well aware of their gang rivalry (and the Jet's racial prejudice) No grown or elder man is going to intervene with gang punks, unless he's a street cop. Let the boys be boys. And Riff's gang didn't trash Doc's store disrespectfully. That was just their meeting spot.
I know that Doc tried to get the Jets and the Sharks to just talk it out instead of rumbling, and that's when Riff told Doc to "kick it". The Jets and the Sharks were determined to rumble, and rumble they did.
