This is why I’m always walking around with headphones on. It’s not just at airports - it’s everywhere now. The no headphones when listening to music, watching videos, playing games, etc is incredibly annoying. Ear buds can be had for as little as a dollar. That being said, I try to avoid confrontation and make as minimal contact with people as possible. Hoodie up, sunglasses on, headphones jammed into my ear canal.
