Today, while waiting for a plane, a man in a wheelchair was struggling to get to baggage, so I helped him. I did so without realising that I passed through the "No Entry" gate. What did I forget? My phone, my ID, and my boarding pass. What do you need to get back to the plane? All of those. FML
Just an extra bit of info: I was with my parents at the airport, so I did make it back... after 45 minutes of going through security and announcing that I was an idiot on the intercom so my dad could save me.
