Hahaha, so true! One person was sleeping in the airport lounge I was at and he kept the whole room awake! Except for the people who were part of the "Earplugs Club", of which I am a proud member, whenever I go to airports (well, okay, I use Airpods Pro 2 and turn noise cancellation on, same thing though).
How did he manage to keep everyone else awake? Was he snoring? I also agree that earplugs and a sleep mask are essential while traveling, just due to how much more important sleep becomes as a means of recovering from stress as well as the unpredictability of the circumstances in which one will be sleeping.
