I surely don’t know what you mean. They’re to keep the raccoons out! That’s why they’re on a piece of velcro, so they’re removable!
Sarcasm aside, absolutely. Even if you wouldn’t get in trouble for people hurting themselves by going into your bins, you could probably get in trouble for messing with town property or something. It’s just the kind of thing I immediately think of after growing up with stories of “Let me take care of that for you” about a guy who’s probably doing 30 to life for prostitution and selling heroin/whatever else the Hell’s Angels get up to.
It really depends on where you live and the kinds of bins you have. I keep my bins in my garage because we get snow (used to get snow? Climate change and all that), and there are times when I can smell even just the normal household garbage inside the house. I also live in a duplex, so my entire downstairs is a single large room with a kitchenette off of it, meaning that when the garbage cans stink, they stink up the entire downstairs of the house.
I think the cans the town uses just don’t have a great seal on them, as I’ve heard other people complain about similar issues with the smell, and my parents even have a separate small can they keep outside specifically for their dog poop that they toss into the actual garbage right as they take it out to the curb so it doesn’t stink up their house.
Luckily, I’ve never had the issue of people tossing their poop into my cans, but I’ve heard tons of people complain about it. People not picking up after their dogs at all, however…that’s a different story that’s so bad around my neighborhood that multiple people have installed signs about it.
