Non-members on CLs

No names (just yet...).

On a CL (which has recently changed hands) the other week when a single guy in VW T5 home conversion turns up late at night and is away again 6am the next morning.  When speaking to the CL owner the next morning I said I was surprised to see he'd let someone stay in a van with no toilet (given that the CL has no toilets).  He seemed a little vague as to whether the person was a club member (I suspect he wasn't).

Is either issue acceptable?  Certainly I think the no toilet issue is a complete no no and I'm not over the moon about letting non members in just out of greed (well what other reason is there?).
