Don't take a shower, get drenched
While on a travel assignment, I was visiting a rather fancy resort where visitors were expected to wash off the sand before re-entering the deck area from the beach. I don't mean a just-rinse-the-feet-type shower, but a full head-to-toe sprinkler system. While using it, I thought that the large showerhead would be nice in my home. This gentle sprinkler that seemed to use a lot of water, actually, used very little.
When I was younger, the showerhead seemed so big and when I turned it on, it covered me with a large spray so I was in and out fast.
