What is it with telephones in hotel room toilets?

In this apparently 5-star hotel I'm holed up in Amsterdam - they have 3 phones in this room and one of them installed by the throne in the bathroom.

Clearly I'm not the target audience for this level of communication equipmentization (I'm making that a word!). I have no one to call on a fixed line whilst I'm doing my other kind of business.

Also I guess most of these elegant boarding houses haven't heard of mobile phones.
