We're having work done on the house. The skip is outside the back door, and the wall between the back door and the house has been demolished for access. There is temporary metal fencing which clearly shows the skip is on our property.
We live along a lane which is popular with dog walkers. Today I opened the back door to take laundry out and nearly stepped in the poo bag someone had lobbed over the fence towards our skip and obviously missed.
Even if it had gone in the skip, it doesn't get emptied every week. So, as soon as something heavy (like construction materials) was placed on top of the poo bag, that's going to go everywhere, and stink. And probably make it harder to retrieve usable construction materials.
What is wrong with people? Don't put your literal shit on other people's property (oh and actually pick it up and take it home with you/put it in a designated bin regardless).
IABU: totally fine to just throw dog shit anywhere, as long as it's in a bag
IANBU: don't throw actual shit onto other people's property. Or anywhere except a bin or your own house (where you can do what you like with it)
