Auf Wiedersehen Pet (1983)

Dennis is getting it together with Dagmar from the site office. He takes her off to a hotel for a romantic interlude. Meanwhile, Wayne and Barry are 'on the pull' and have met up with a couple of Swedish air hostesses staying at the same hotel. Oz decides to play a practical joke on them, so he rings the hotel and leaves a message telling Barry and Wayne to go up to a particular room. The room is occupied by a German couple who think they're being mugged. Wayne and Barry have to 'do a runner' from the hotel. Their escapades ruin Dennis and Dagmar's chances of a romantic evening.
