Retailers, beware. The Big Customer is watching you! And takes pictures. And blogs.

Paul at Hee-Haw Marketing went shopping at Kohl's and shared his impressions.

A blogger keeps a watchful but friendly eye on McDonald's over at McChronicles.

The Kohl's picture was not as effective as a customer may have just shopped through the clothes. It may be difficult to keep them straightened. The Wal-mart photo seems more serious as it shows a lack of ordering as well as stocking.
