What are you doing here at this time?

The night porter in a Welsh hotel saw to his surprise one of the guests coming down the stairs in his pyjamas at four o'clock in the morning.

Tapping him on the shoulder he asked "What are you doing down here at this time?"

The man started, and looking hazily at the porter replied: "I'm sorry, I'm a somnambulist."

"I don't care what chapel you belong to", said the porter, "you can't go wandering round the hotel like this."
