Why don’t they use them?

Maybe he thought his big workman's hands were unworthy of fresh pretty towels. I found that guests disliked my clean textile table napkins and are happier with paper ones or paper towels.

On a lighter note, I had a woman friend who refused to wash her hands after her weewees because as she said men don't wash after weewees. I never spied on menfolk in my own house and have no evidence either way.

many men never wash their hands.

He has probably dried his hands on toilet paper and flushed it.

No point in being annoyed, just wash the towels, as you say you will when he’s gone. I’d sanitise the loo area too, and anywhere he’s worked.

@tanith I would have done that but didn’t anticipate him being here long enough to use the loo! Towels will be straight in the wash once he’s gone!

I’d just remove my personal towels while he’s working.
