This Is Why The Cabin Crew Members Hide Their Hands Behind Their Backs???

If you have travelled by air then you must have observed that the cabin crew members always stand at the entrance of the aircraft and you would be thinking that they are there to greet you with a smile on their face.

But there is one hidden thing to it and that is that they have a device at their back which they use to keep a count of the number of passengers entering their aircraft. They keep on punching the button of the device for the count and we thought that they are there to greet us. We have provided you a simple video to demonstrate the same so watch it know the reality.
