It depends.
If you're the first guy of the day she might put a new sheet on the leather bed thing they all use.
Some are just filthy though as I remember seeing an old cum stain which I had put there a week later
you don't want to be using a UV light to see the stains...

(This is why I sleep on the floors of hotels! I'm serious)
Towels also depends... washing a shit load of towels costs money. Michelle even had a washing machine in her own room.
As such some WG think it is cheaper to simply dry them and re-use. As such I NEVER put my mouth near the towels and prefer to use a moist towellette generally taken from KFC or Watsons to wash my face.
