Visitor and Peon

A visitor came to an office and before entering into the manager's cabin,
he asked the peon who sat near the enterance,
"Is there anybody inside?"
Peon told 'yes'.
Visitor waited for half an hour no person coming out of the room
and asked the peon 'Hare! who is inside?'
Peon calmely said 'Who! manager only"!!
