Have a cup of tea

JOSHU asked a monk who appeared for the first time in the hall,
“Have I ever seen you here before?” The monk answered, “No sir,
you have not.”

“Then have a cup of tea,” said Joshu.

He turned to another monk. “Have I ever seen you here before?” he
said. “Yes sir, of course you have,” said the second monk.

“Then have a cup of tea,” said Joshu.

Later, the managing monk of the monastery asked Joshu, “How is it
that you make the same offer of tea whatever the reply to your
question?”

At this Joshu shouted, “Manager, are you still here?”

“Of course, master!” the manager answered.

“Then have a cup of tea,” said Joshu.
