Well, it was at DXB immigration and it worried me quite a bit! I don't like any complications when it comes to immigration or customs, especially in places where they don't mess around.
But I also provided useful knowledge to all of you out there that the eGates contain some kind of proximity detectors if someone ever encroaches on the space inside the eGate and how it would lock you out. I imagine most people weren't aware of that and have never experienced such an event.
You're welcome!
