"The '6 Schwedinnen' (six Swedish girls) from the title clearly had no need for further sexual education (that was completed in their previous adventure '6 Schwedinnen im Pensionat') and now they have to work for a living. As petrol station attendants!
Their customers can expect to be treated very, er, lovingly, in fact the girls seem to make love to all their customers. Such loving care is sadly lacking regarding the safety of the whole enterprise. While the customers are attended to, inside the station, the completely unattended petrol pumps keep running and are highly likely to overspill - one of the rare situations in which premature ejaculation can save your live, because you might just get back in time! To top it all, several of the girls are heavy smokers. Miraculously nobody gets hurt.
