The interruption was the stressed out looking blonde assistant who, upon closer inspection, was actually a pissed off teenager. Cassie was about a head shorter than all three men but the look on her face showed she was prepared to kick all of their asses. It had been a pretty sucky day, and whatever the hell this was definitely wasn't improving her mood.
"Break it up, guys," she instructed, hands on her hips. The businessman not fighting the disheveled looking guy protested that they hadn't started it and anyway, that dude broke the other dude's phone. Cassie did not care. "Send the bill to Stark Enterprises. And leave, before I call security-" or grow a couple feet and throw you out of a window she thought.
The suit who'd complained made a move towards the door but the other one didn't seem to want to stop his fight. Calling security required returning to her desk and then they'd have to actually get up here. It was kind of a hassle when she could just stop it herself. Cassie mulled over the situation for a moment and finally figured that, even if the man decided to file a law suit (he looked like the whiny type), with security footage they probably wouldn't find that the girl had done anything more than tap him on the shoulder. So she moved behind him, and jabbed her thumb into a pressure point near his neck. Apparently, all those martial arts classes her mom had made her go to as a kid were as good for dealing with belligerent businessmen as they were for dealing with kidnappers. The guy yowled and turned on her and, unimpressed by his rage, she simply said, "Security will be totally worse, man."
