"And how long do you think it'll take to pay them off selling fake papers and exploring the same local dungeons? Like I said, if we find some treasure - and I'm not saying we absolutely will but there's at least a chance I'm gonna wind up doing some dungeon crawling at least once before this is all over - I'm willing to give you a chunk of the rewards to help pay off your debt. Anyways, this will probably take me just about the rest of today. Since I'm only going to try to get you the robot if you decide you want to come with me I'll call you before I go to the mechanic's, that'll give you some time to think about it. In the meantime you've got some more potential customers you might want to go talk to in case you decide you'd rather stick with what you're doing."
Open up a window which follows me as the line moves, but rather than use it to access the interface play a game on it. Even if there's a chance of having the wait get timeskipped if nothing else interesting happens in line I might as well say how my character's passing the time.

"Mr. Fuzz and Peri Gren, pulled in by spacial displacement and trying to learn why. No felonies to declare, but can I see a list of what else might need to be declared?

"No illegally smuggled items, but we are in possession of legally owned weapons we would like to register for personal use as part of our jobs."
Summon the WoP Spear and place it on the counter along with Peri's pistols.
"Is there a registration fee we need to pay or is it more of a 'make sure these weapons are known about so you know who to track down if they go up for sale illegally' kind of thing?"

"Alright, next stop is the mechanic's workshop."
"Surely you can't be serious. We spent all day waiting in that kind and now you want to perform physical labor without so much as a moment of rest?"
"I am serious. And don't call me Shirley."
Go to the Mechanic.

"Hey, need an extra pair of hands or two for anything?"

"That depends, what kind of machines are we talking about?"
