Silks, A Bully and Me

I saw these ephemeral wind caught synthetic silks blowing in the wind in front of a cheap and (what I thought) cheerful fabric shop today. I was horrified and maddened to hear, from the gloom of the interior, this huge bouncer-type approach at me with the less-than-charming "Fuck Off!". WHY??? These rolls of fabric (unpriced, so no commercial espionage excuse here) where on the public footpath, I was on the public footpath. I seem to attract this type of behavior, is it me or them?
