I have various guests popping in and visiting my home, often unannounced. For this purpose I purchased a collection of "guest towels" from M&S.
I keep a clean towel hanging on a dedicated hook next to the bathroom sink so it's ready when visitors just pop in.
BUT... no-one ever uses it! I discover my guests have used my personal towels to dry their hands (which they have to walk across the room to do); my bath mat, my flannel or they come back into the room wiping their hands on their clothing.
How do I get people to use my guest towels? I was considering purchasing a paper towel holder like they have in public loos but that seems excessive.
