A sardar is traveling via train. On his way, he feels the urge to go
to the bathroom. So he goes and opens the bathroom door, which
happens to have a mirror in the front. The sardar thinks there is
another sardar bhaiwaal in there, quickly shuts the door and returns
to his seat. 5 minutes later he goes again, only to find the same
sardar bhaiwaal. An hour passes away, he's made 20 trips to the
bathroom, only to find that the same person is still there. So he
finally gets ticked off, goes to the last compartment and tells the TC
(Ticket Checker) what's been going on. The TC, which also happens to
be a sardar, feels bad for him and promises to throw the bum out. The
TC walks down to the compartment with the troubled bathroom to get the
resident bhaiwaal out.
Few minutes later the TC comes back and tell the sardar "I'm sorry, I
can't do anything. The guy in there is a railway staff member".
