The sign featured above is very interesting. If you were to take it literally, you would never feed pigeons again. Just like when you warn a child not to talk to strangers, you mean for that child not to talk to strangers anywhere, under no circumstances. Imagine a sign telling you not to feed pigeons anywhere, under no special circumstances. That would be a strange sign indeed! The definite article is often omitted from signs so as to save space, this also appears to be the case with the above image. If the definite article were included, it would read:
Please Do not Feed the Pigeons in this Area
