Rats invade a convenience store in Japan!

You've no doubt heard of the movie "Snakes on a Plane," right? Well here is a new one..."Rats in the Convenience Store!" This time however it is very, very real. This is a store in Tokyo that seems to be experiencing a rodent problem in a BIG way. At the last count, I saw 7. I particularly like the little guy that came out of the 3rd shelf down and climbed up the side of the cooler to get back in on shelf number 1! What do you do in this instance? SURELY the store is aware off the pest problem! Clean up on isle 2!
