I was on a business trip to the US recently. In my hotel there was a typical sign saying: save the planet by reusing your towels; hang your towel if you are happy to reuse it.
Day 1, I hang my towel rather messily and I get a new one.
Day 2, I hang the towel quite neatly and again I get a new one.
Day 3, I hang the towel neatly and put the sign on top of it but I still get a new one.
Any tips on encouraging a hotel to actually follow its own stated policy?
