Putting rubbish in someone else’s bin

It wasn't shit. It was general rubbish and it was outside the persons house. I'd have been grateful

I live in a rural area, walkers are always putting stuff in my bins. The problem is they pay no attention to which bin, so I'm always having to fish stuff out and put it in the right bin. I even once had an entire shopping bag of food wrappers and nappies put in my garden waste bin which was already completely full of grass cuttings, so dead obvious it was the wrong bin. We get fined here for wrong stuff in wrong bin. Not saying you got it wrong OP, but honestly, I wouldn't use someone else's bin, I do think it's a bit rude. They don't know what you put in there and it could've been a problem they needed to sort. I appreciate that in this instance it probably wasn't the case.
I do think you did a nice thing on picking up the litter though. I normally just take it home with me when I do a litter pick, and put it in my bin, which is what our local council advise.

This

It irritates me when people put small stuff in my bin as I’ll put bags on top, they’ll squash the item/s to the sides or bottom and then they don’t come out when the bin is emptied. And then I’ll have to do bin fishing at a later date. I only put stuff in large bin bags in my bin and don’t want anyone meddling with my system and creating work for me.

Also
It was their private bin not a public bin.

This would give me the rage, too.

YANBU for picking up rubbish
But YABU for putting it in someone's bin.

Really ? We had to buy our bins when we moved in so I believe they are ours

Even if it was dogshit, what's the issue? Not like they sit and have a cup of tea in the bin?

well your sentiment is along the right lines, but op used someone’s private bin and that isn’t ok

Of course it looked like you were putting dog shit in it.

You shouldn’t have used their bin I don’t think. Although you tried to solve a problem, you did involve something (an item) that belongs/is meant for the use of that particular household.

so overall, either take the rubbish home with you or leave it.

I do this. Pick up a random bit of plastic and put it in the closest bin. No one has ever told me off and I wouldn’t expect it. If they thought it was dog poo I can see why they’d be upset though. I’d probably just have put the eg random crisp packet abd plastic bottle in by themselves, without the dog poo bag

You did a good thing by pickling up litter but you either need to take it home or put it in a public bin. You don’t put it in a complete stranger’s bin.

If you want to get technical about it, it could apparently be considered fly tipping, so not allowed. However what kind of miserable person would actually throw a fit over you putting something like that in their bin. It's not like your chucking a massive bag in there,taking up space.

Like you say, you are just trying to help out keeping the neighbourhood clean and what else are you meant to do with it. I do the same as you Op when I see rubbish lying around, rather than leave it around for wildlife to find or to polute the environment, I pick it up and put it in the nearest bin, because no I'm not going to walk around the whole hood with my arms full of other people's rubbish until I reach home and can throw it away there.

OK technically the council are meant to deal with it, but it's just common decency to want to keep the street clean when you see it and not have it blow away or go down the drain. If everyone did it, this wouldn't be a problem.

I can see why they thought it was dog shit, and some people are weird about their bins. I’d have carried it home or to a public bin.

no good deed goes unpunished op

I'm with you. It really doesn't matter if a few bits of rubbish go in any bin.

I pick up bits that have blown directly into my garden and along the boundary wall but otherwise we are advised to report it since it’s their staff who made the mess.

its not their bin

I despair sometimes. What we need is more people like you who see a problem and think how can I make things better?
Instead everyone expects other people/the council etc to sort it out.
Well done op; ignore the miserable git.

I can see why they thought it was dog shit though.

I’d of reported it to the council for the cleaning team to deal with as it was mess made by the bin men.

We actually have an app to report issues like this. Means the bin men also get a reminder to be cleaner while working.
