I recently saw a new twist on advertising in bathrooms -- flat screen video. Your intrepid blogger took incredible risks capturing this photo for you inside the ladies room.
A second terminal was kindly placed outside the ladies room (below), no doubt to serve the ever-present line-up of women, or perhaps their male partners who are patiently waiting for them.
Anything that can reduce the annoyance of waiting is usually a good thing for customer experience.
As every space your eyeballs may roam continues to be colonized by commercial messaging, it is going to be harder and harder to be heard by anyone at all.
