Denied access to toilets

I suppose just emptying it in the next available toilet when you arrive at a place that lets you use the loo is feasible. .

No it’s not feasible! Campsites have specific facilities for emptying chemical toilets, just emptying in a toilet would be disgusting for the toilet and would also not properly clean your chemical toilet.

A campsite portable toilet facility is; a waist level sink, with a big hole to accept the waste, and a hose pipe used to rinse your portable toilet/tank and the sink.
