I have stayed overnight in your house and have had a refreshing morning bath. How would you expect me to dry myself?
With the towel carefully laid over my bed before my arrival
With the towel handed to / indicated to me when I said I was planning to bathe
With the clearly marked guest towel
With the towel in the bathroom that looks most likely to be appropriate
With the towel that I have brought with me
With random items of clothing I have with me / the handy roll of toilet paper in the bathroom
By frolicking naked in the fields outside
Hang on - we don't have a bath
Hello, police - there's a naked man in our bathroom...
ETA: If you're visiting my household, the choice is between using one of the towels which I use hanging up by the foot of the bath, or one of a pile of freshly laundered towels sitting by the sink unit. I don't have strong feelings either way. I do, however, recommend against frolicking in the fields as the queen takes a dim view of nakedness in Windsor Great Park.
