BERLIN (Reuters) - A young German couple hid in a bed shop after closing time and passionately tested the water beds for several hours before being caught by police, officials said Wednesday. The couple, aged 17 and 21, were discovered by police in the western city of Porta Westfalica after shop alarms went off as they tried to leave through an emergency exit at midnight. Police said the shop did not press charges against the couple and police let them go with a warning about the costs of false alarms.
