Tirez l’eau
When I was very little back in England we had indoor toilets like that, but very posh! They had polished wooden seat area so you couldn’t actually see the toilet. I had a Swiss nanny who used to tell me to “tirez l’eau” - pull the water.
Bins need to be put separately with plenty of space between them. How else can the bin collector handle them. Our council has strict guidelines for this. As for putting them in front of the post box - words fail me !!!
