Joginder Singh was at the International Airport at Delhi along with his wife and two sons to catch a flight to Abu Dhabi, as he had got a job there.
He saw a machine with various colorful bulbs glowing, which had a message stating "Insert One Rupee coin and I will speak the truth".
Joginder inserted a coin then the machine said "Your name is Joginder Singh and you are catching a flight to Abu Dhabi".
Then his wife inserted a coin and the machine said "Your name is Smt. Joginder Singh and you are catching a flight to Abu Dhabi".
He experimented with his two sons and got truthful replies. Joginder still could not believe this so he again inserted a one Rupee coin in the machine. This time the machine said "You are Joginder Singh and you have just missed the flight to Abu Dhabi".
