One thing the Doctor doesn’t like about earth is humanity’s reliance on bureaucracy. Earth isn’t the only planet in the universe where those in charge seem intent on tying themselves and everyone else up in miles of red tape and impenetrable legal jargon, but humans have an undeniable talent for it.
They’ve created thousands of laws, and generated mountains of paperwork pertaining to them, mostly forms that have to be filled out in triplicate. Worse, every country has its own laws that tourists from other countries often fall foul of through ignorance.
Honestly, it’s a wonder anyone gets anything done.
