Is a trash can a good place to find good food?
Is a clear-out bin/shelf at the grocery store a good place to find nice things?
You may find a nugget, perhaps, after searching, rummaging, checking expiry dates, etc., and spending hours and hours doing so, over multiple days/weeks. But you are also more likely not to find a nugget, for the simple reason, that nothing of any value is trashed or thrown out to the dogs.
Use your mind.
