Datamuse, I agree. That would be crappy (hehe).
But the OP's rant (which was unconfronted, mind you) was against someone that did this "horrible" deed either late night or early morning BEFORE the garbage man came to take the crap along with their crap.
So my point is...who cares?! Seriously, there is dog poop sitting in your garbage can for two hours? And that's a big enough deal to write a rant about on the WSB why?
If you really don't have anything better to bitch about than temporary squatting in your garbage can, then I have no sympathy for you.
I think it's even fine to do it when the garbage truck is not about to come, but the person leaves their garbage can permanently in the city right of way, accessible to anyone who walks by. As long as it doesn't take up a significant amount of room in the can, I say if you put a city-owned can on city-owned property, then it's free game in my book.
Especially for those of you who leave your garbage can on the curb for 3 days. You know who you are...and you may well find my dog's poo in it after 48 hours. In a neatly knotted bag, of course...
