Goddamit Bill, your space passport is due tomorrow!
you clearly didn't remember that your earthling country passport is valid to travel to our glorious international commute station, but that you need a Interspatial International Passport (IIP) to get out of the earth's orbit!
You are now stuck a Saturday afternoon ( Local time ) in a waiting room near the main hall, expecting a video call from your representative in the GESA (Global Earth Space Agency), who will inform you of the procedural of requesting a new passport. You're lucky though, there's a lot of stores, ATM's and atleast two restaurants of each type of cuisine in the solar system. Guess you won't fly until monday, atleast.
PD: Another option could be : Hey, you didn't vaccinate for Mars Flu, you can't board until you visit a medic practician, and they're all off until monday.
