"He felt that he found a creative way to thumb his nose
at their 'No photos' policy."

How nefarious!

I took a photo inside a Fry's Electronics store, back when I did not
know they had a policy against it. I soon found out, as someone walked
up to me and told me it wasn't allowed. No one tried to get the single
photo I had taken, though, and I still have it.

But, see, Fry's lets people take cameras inside their store. I have to
get a yellow slip with the serial number filled out before I go into
the main part of the store, but they have never given me any trouble
about carrying a camera around inside the store. Most merchants don't
give me any trouble for it.
