Spotted?

I was wandering round the market, and there were several scenes which I found interesting photographically. This stall which had hundreds of vinyl records for sale was one, with several customers (generally middle aged men) browsing through LPs of music from their youth.

I was generally shooting "from the hip" - ie pointing the camera in the right general direction while it was hanging from the strap round my neck, not looking through or even at the camera, and just pressing the shutter release when I hoped I had a reasonable composition and a vaguely interesting shot. However, this stall holder is still looking at my camera a little suspiciously! Do you think he spotted what I ws doing?
