[Sheldon doesn't even really remember choosing to pick up the ticket. He must have, sure, but the fact that he wasn't really thinking about it when he did so just means that he doesn't exactly appreciate being tossed somewhere with no prior warning. Maybe if there'd been fine text attached to the ticket, or something, but there wasn't and that means that he, someone very important, has been pulled away from his equally important business to be taken to some-- some lousy amusement park.

He won't stand for this.

After a solid minute or so of tossing himself against the portal with increasing force he finally gives up and seeks other tactics, namely marching up towards one of the figures milling about watching the new arrivals and pointing a finger directly in their face.]

I want you to go to whoever's in charge of this """Progress City""" and tell them-- [hm, actually,] --well, first tell them that I should be put in charge instead. Then tell them that I demand to know what is going on!

[Yeah, that sounds good. After that he's just gonna. Sit on one of the benches, arms crossed impatiently and glowering even though his threatening clearly didn't prompt anyone to go retrieve whoever's running the place. This is fine. He's got a handle on the situation.]
