I was skeptical about the pharmacy story, too, but apparently it's not just an Internet urban myth.

It was reported on "My FOX New York" which I assume is a local version of Fox News. They give names, dates, places. You can read a text report and view a video at this page.

As far as I can tell, the story is based entirely on statements by the woman who was suffering an asthma attack and her boyfriend; that is, there were no independent witnesses. The store manager refused to comment.

The woman admitted that she had been having asthma attacks every day for five days, yet she left home without her inhaler.

The Toronto Sun picked up the story. They don't cite any source, but they don't give any facts that weren't in the Fox story.

I can't find any other "major news source" that has covered the story, but it is being mentioned in lots of blogs and web sites with names like "dagblog" "Gawker" and so on. I assume the Fox story was the source for all of them.
