[prompto feels like he's seen these posters everywhere. as a civilian and your every day joe, he doesn't mind them. as a part-time employee at the electronics store, it's kind of his job to go up to the girl carrying the posters and say the following:]

Hey... Manager says you can't put the poster up here without permission.

[on the window-wall by the entrance. prompto's smiling and trying to appear amicable, because he doesn't mean to come off as intimidating at all, for one. he points inside, and continues.]

We got a security camera pointing out from the inside, and the poster kinda blocks the way. Security measures, y'know. Mall policy.

[before her face even has the chance to deflate, he adds,]

We have a bulletin board inside, though! If you'd wanna put it there instead.
