Actually, it is a very fast way of doing all the clothes at once. If you get there early enough you can fill all the machines you want.
So, here I am right there when the doors open. I pile all the clothes into three machines. Plunk my quarters in (yes, you have to have quarters). And now I'm ready to do some erands. There is a Dollar Store close by, Donut Shop, and my grocery store. The wash took 37 minutes. That gave me just the right amount of time to get some last minute items for our daughter's birthday dinner. When I got back I forgot to push start on the last machine - eek! The owner was nice enough to start the machine, after he saw that the light was flashing. So, I ran home and put the ice cream in the freezer and headed back for the last load.
Then I noticed that I was the only one who had a "cute" laundry basket. The other gentlemen came with plastic garbage bags and a suitcase (?). You meet the nicest people in the laundry mat while washing your clothes.
