You can never have enough...

[Outsider]

Our new bathroom fans are noisy but very sucky, and a pain in the night because they are linked to the light switch. They are actually so noisy most of us try to avoid using them in case we disturb our nextdoors (these places are awfully close together!) But - one neighbour is very pleased with hers. She hangs her washing up on a pole stretched across the shower box at night, turns the light on, closes the door and lets it run all night, and tells us blithely that it dries her washing beautifully...

This is in spite of the fact we have two very efficient dryers in the community laundry.

Honestly, sometimes the folk around here just astound me.

You should tell her this (though she probably wouldn't listen): 
"Experts agree that you should not leave your bathroom fan on all night. You should only run the fan for about 20 minutes during and after a bath or shower. You especially shouldn't leave it on at night. If it's run too long, it can cause serious problems and become a fire hazard.

Hope she also has a fire alarm too?
