I know its easier for a single guy like me, but my wardrobe consists of a load of whites and a load of colors. Colors are jeans and colored T Shirts. Drying always take more time. So I take a lawn chair with me and a book. Then sit outside and read, checking the machines every so often.
If all the dryers are full when my washing is done, I don't have a problem unloading a dryer into one of the rolling carts. There's no excuse for leaving clothes in a dryer. They all seem to have signs reading "$.50" for 10 minutes or something. Wear a watch.
