BERLIN - A German couple are demanding compensation from a tour operator because a maid repeatedly interrupted them while they were having sex in their hotel room during a holiday in Cuba, a court spokesman has said.

The man and wife filed a lawsuit at a district court in Hanover seeking a refund because they said the maid walked in on two occasions while they were engaged in intercourse, even though they had a "Do Not Disturb" sign outside the door.

They are seeking about $4,000 (2.500 pounds) in damages from the TUI holiday company. But TUI has said the hotel's failings only amounted to an "inconvenience" and did not warrant such high compensation.
