Outlets are a form of currency. Especially at an airport. There are times when they are all taken and I'd trade my first born child for a charge. There are just some places that especially need outlets. You've got to have an outlet close to your bed. How else are you going to keep your phone charged? That's the only way you'll be able to enjoy scrolling through instagram while you ignore your significant other right next to you. Don't act like you don't do that. Try leaving your phone in the living room for once (unless you live in a living room like I do).
People are so petty about charging their phones. They'll unplug your phone without even telling you just so they can go from 89% to 100%, even though your phone is dead. It's still the wild west with phone-charging etiquette. Be safe, people.
