Quinn takes a note of these bills of sale on his compad (either by taking pictures, if it has that capability, or by typing out the relevant information if it does not.)
(Do the documents say where the purchased items were sent to?)
After that, he'll place the bills back into the file cabinet, then grab the closest folder of papers in the same drawer, take both them out, and close the drawer.
"Found what I needed," he'll say to the overseer with a faint smile and chuckle. "Some offworlder's kid got their identity stolen, and it seems whoever nicked it used the name for a few investments here. No need to worry; there shouldn't be any more trouble for you on the matter."
As he slips the folders and his compad into his backpack, he slowly walks towards the overseer's desk. "Now, is there still any coffee left in the pot?"
