Agreed. And your solution is what exactly tony???
that is the 1,000 doller question.
a friend of mine who owned a shop had a problem of someone dumping bags of rubbish in the litter bin outside the door of the shop.
he kept an eye out & discoverd who was doing it.
the next time the bag of rubbish was left he got in his car & hung the bag on that persons gate before he got home.
that was the end of that.
it would not be practicle to do that in the case of someone emptying a toilet from a camper as they could be from the other end of the country.
i think if we see someone doing something like this approach them & politly without arguing point out what they are doing wrong & ask to please not do it again.
if they argue with you & tell you to mind your business or something similar tell them you are reporting them & do report them hopefully with pictures & reg no.
i drive a motorbike, on 1 occasion i had a driver flick a lighted fag butt out the window in front of me.
when i pointed out what he had done & the danger of it he was so sorry as he did not realise he had done anything wrong.
sometimes the polite way just might work instead of barging in like a raging bull.
