I found two examples of thoughtless acts, illustrated below.
While walking around the north side, I noticed a garden hose with its attachment placed on a small curved surface above it, attached to the wall. I'm not sure what the original purpose of the wall attachment was, but it's unlikely it was designed for this purpose. However, it's useful for keeping the hose attachment near the hose.
I carry my headphones with me, but the cord causes problems because it's six feet long. I've taken to wrapping the cord around itself and putting the headphones into a plastic bag so the cord won't get tugged by other objects in my bag.
