My biggest complaint about using a laundromat in the 70's and 80's was how long it took to dry the loads. I did notice at one point the laundromat management had turned down the heat on the dryers, so it took a lot longer. Plus the machines only took dimes (at the time) and it would take a fistful of them to get the load dry.
What might make more sense if for a laundromat to charge by the pound. You walk in, put your laundry on a scale, and pay per lb. The washers and dryers after that point are not charged. You can bet the laundromat would get the most energy efficient machines in at that point.
