Towels have to be hung straight and flat to dry quickly and not get stinky, especially for re-use. I don't like leaving a damp towel in the humid bathroom towel rack so I usually hang the hanger on a hook just outside the bathroom door. If the towel is directly on a hook, it will be bunched up and not dry properly and installing a rack of some sort isn't exactly easy so a "hanger" provides a straight line where we can hang towels flat. I used to hang the hanger with the towel on the handle but it was a bother to move it every time I needed to get something from the cabinet so I stuck a hook on the side. Not pretty but VERY convenient!
Inside the closet??? If there was nowhere else to hang the hanger and the closet door was left open.... not ideal but could work I guess 🙂
Also, this is probably just me...... but I personally like to hang things on hangers rather than hooks.
FYI, pics are of my weekday company-provided (ugly but furnished and free) apartment where I stay for work during the week:-)
This is how I hang things. For real~
