I turned around and espied a laundromat. It has been years since I have set foot in such a place. It was an eye opener. It cost 3 quarters for one pouch of laundry detergent! Lesson here - bring your own detergent.
The ladies on the right were showing the young girls on the left how to sort laundry. There was a lot of laughing going on. As you can see from the sign, it costs many more quarters than I had to wash and dry one load!
They made sure to pack in as many articles of clothing into the washer as possible. (I wonder if any of it really gets clean jammed in this way.)
I decided not to do laundry, make a phone call or fill the tires with air. I still have my 4 quarters. Since I cannot do much with them anyway, I'm going to put them in the bank and save them for a rainy day.
