Try the United Kingdom for nonsensical quarantine rules. Enter the UK from a red or amber area and undergo quarantine but, as you are flightcrew, you are allowed to leave quarantine to go to work. Then you can fly back to the very place you’ve just had to quarantine from but upon your return - because you are now entering as crew - you have now been cleansed of potential COVID and the slate is wiped clean, no further quarantine period. And no I am not making this up.
