So, OK, some guy walks into a shop, picks up a painting, turns around and walks out while the store person had their backs turned.

Good job!

Many times have I thought of this method... reminds me of Bill Murray doing it with the security guards in Groundhog day :-)

And as far as the shop person moaning... well tough titty I say, $5k for a 1 metre square painting? you gotta be joking... In this day an age with the world economy in recession, you still want to charge that? Good luck.

and Kudo's to that robber... you'll probably get caught... but hey nice try ;-)
