I’ve sat at gate 16 for 2 hours and watching a video,  drinking coffee and taking it easy.  30 mins before the gate opens I decide I will walk the short distance and find a comfy seat as me arse is getting a little sore. On arrival I discover the gate number has changed to 211. Thankfully I have plenty of time to get to the other gate but if I hadn’t checked when I did I could have been up shit creek without a paddle 😆
