Here is where you can get a bit of info on how our few specific NPCs! More may or may not be added later.
Owner
Our most generous entrepreneur, a connoisseur in prestigeous fast food culinary arts. The boss believes that the costumer should utmostly get what he or she wants! There is a Picasso style painting of the owner near the counter for all to see. It's not clear how this person looks like, but it's really clear that they really like rainbows!
The Janitor
Your friendly neighbohood janitor's here to keep the place spick and span, so don't mind the eyes staring at your soul, he's (?) just calculating how much of a mess you'll be, you slobs. Personally designing the janitoral outfit, he'll take offense to insults made about it! Noticeably, the Janitor is also very fond of pink.
