What she describes in the first few paragraphs of the article is obviously horrible, but the closing paragraph, which you quote, is also totally insane.

I was in London a few weeks ago, meeting some clients; my aged iPhone had run out of battery and, not being blessed with a watch, I had no way of telling the time (yes, this is a stupid situation and I felt like an idiot). I was loitering outside my client's offices and knew it was roughly the right time because the coffee shop I'd been in just before had had a clock, but I didn't particularly want to arrive overly early. A person, who happened to be a woman, walked past me, and I stopped her, politely, and asked her for the time, which she duly told me. I thanked her and she went on her way.

Does that count as harassment or threatening behaviour? After all, I'm a white male, a little over 6ft tall, with a shaved head and often a beard, and she was a woman, alone, probably walking to or from her office.
