If you were the driver of an Eldis Compass on the A68 south today at 11.45, thanks for driving with you grey waste open, I was stuck behind you on my motorbike and had to put up with the spray until I got past you, the title says it all
Must have been a big waste tank because mine is empty after about two minutes and empty tanks don't spray water out when they are empty, Wasn't it a short time ago the government wanted you to share baths and put the water on the garden to keep it moist? Mine has water which is slightly soapy and minimum residue in it perhaps the one being followed had BR train type toilets on board then you could complain. they must have just pulled out or very slow leakoff.
He might also have been completely unaware it was open. A joker might have done it for a laugh when he was parked in say some services for example or it may have just been absentmindedness (if that's a word).I'd put his reg number up, but I was on my motorcyle so couldn't write it down and I can't remember anything since my stroke last year
