No kidding.
But I do wonder what they could have done, if you're stuck in a foreign state like this:
- Camp out in SFO for 1 month, until you test positive. Likely infecting all airport pax around you
- Attempt to get a hotel reservation, which is unlikely. If you do, potentially infecting the entire hotel by way of HVAC (if you watch one side of the media at least!). Likely this would cost more than they can afford.
- Flying home, and quarantining. Perhaps, it was the lesser of the evils after all...
