Sardarji and a Barber

Once a Sardarji was travelling in a train. He felt sleepy so he gave the guy sitting opposite him on the train 20 bucks to wake him up when the station arrived.
This guy was a barber, and he felt that for 20 bucks, the Sardar ji deserved more service.
When the Sardar ji fell asleep, the barber quietly shaved off his beard. When the station arrived, the Sardarji was called and he went home.
Reaching home, he went to wash his face, and suddenly screamed.
Said his wife "What's the matter?"
Sardarji replied " The cheat on the train has taken my 20 bucks and woke up someone else."
