The rota

A friend recently recounted a bizarre story she had heard from a (female) friend who was in a band with a load of blokes. When the band went on tour they would often find themselves all sharing a room. The first thing the blokes would all do is draw up a rota, allocating each of them a time-slot during which they could perform solitary activities of an onanistic nature. The woman member of the band was not included in the rota but her husband was; she did not think any of this strange.

I myself have never been in a band but I know that some readers have been. Is it normal for touring bands to draw up a rota of this kind?
