I just used to call it "a quick shower"

In this camp site you have to press a button to start the shower and then the water runs for exactly 15 seconds. I pressed it three times during my shower yesterday: water - shampoo - water - shower gel - water. That amounts to approximately a minute. Then I pressed it again and treated myself to just standing under warm water for another 15 seconds. I used to think of this process as "taking a quick shower". Now it's my "me time". Realising this made me laugh. Fake laugh of sadness.
