No jokes please - it’s actually a serious question. We’ve just spent 2 months in France, Belgium, Luxembourg and Germany. Of course one pays to empty the toilet cassette - but it’s possible without paying to stay overnight. We’re heading back to park up for the winter in Kent (‘cos we live there) and might have some deposits while travelling. Is there a motorway service point? Not that I can find. Even the usually useful P4N can’t suggest anywhere other than a full-scale campsite (most closed). Is England too stingy to deal with our needs, or is it just Kent, or am I missing something? Suggestions other than illegal dumping would be welcome. Or I’ll take it home in the boot of the car.
