think Jonghyun was not yelling at the staffs, he was acting angry with Minho lol.. Minho was being a little too nice here (he's a gentleman after all), asking Jjong to go in a little further and then asking members to follow the staffs' instruction to give the seats to T-ara. And he was definitely not really angry, look at that "0-mouth" face with a little smile he had after that. If you're really angry, you wouldn't make that face. ^^
