Sasuke might have, perhaps, been more awed by Jiraiya if he hadn't had Tsunade as a master first. As it was, the clan-trained respect for his elders was most of what stood between him and raising an eyebrow at the white-haired man posing in front of the gate. He managed to retain an expression of polite disinterest, hand still extended.

"Papers," he repeated. "Even if we recognize you, Jiraiya-sama, the procedures are in place for a reason."

Not that Tsunade seemed to put much stock in doing anything other than wandering flagrantly in and out of the village as she pleased, but Sasuke was reasonably certain that she at least generally expected to be recognized without a song-and-dance routine to announce herself. (It was difficult to imagine Tsunade together with song-and-dance in the same sentence, really, though song alone was not completely unheard of after enough sake.)
