However, luckily there were some kind people on-board, with another passenger swapping her window seat with Douros so that she could continue to feed Archie.
And then, in an ironic twist of fate - or perhaps karma - Douros got revenge without having to lift a finger.
The woman who had made the ignorant comment ended up leaving an item behind on the plane, and Douros didn't jump to tell her.
"I should have told that old bag she left her reading glasses on her seat, but I thought to myself she really should have put them away BEFORE she rushed ahead of everyone to get off the flight #gladthatisover #goodluckfinishingyourbooktonight #normalisebreastfeeding."
