I was traveling through Istanbul and there were multiple tiers of security before reaching my plane. One of the checkpoints was run by private security, and they took my laptop out of my bag and asked me a ton of questions. They asked me to open my computer and log in so they can review data in my machine.

Lucky for me, my laptop was completely out of battery, so when they opened my MBP, all they saw was the red blinking battery symbol. They mumbled to each other under their breathes, handed me my laptop, and waved me through.
