I live in an apartment complex with several communal laundry centers.
There’s two rows of washers and two banks of dryers.
The washers take 30 minutes to run and the dryers take 60 minutes.
So, on a busy laundry day, wet laundry piles up while I wait for a free dryer.
The problem is compounded by people who don’t collect their stuff from the dryers for an hour or two.
I use a kitchen timer for my own laundry when it’s in the dryer so nobody gets stuck behind me longer than they have to.
We really need a house.
