While I understand "wanting to look around" these guys were literally just standing around chatting in front of the portal for a minute before we reminded them to get in the circle. That is what was met with the defiant "We just aren't going to let anyone advance floors" bullshit. I don't think it is unreasonable to want to continue advancing when they were doing nothing otherwise. It is unreasonable to simply sit around doing nothing and holding up your group mates just so you can find an excuse to get huffy and ruin the run for everyone.
