I went to a Dunn Brothers coffee shop the other day to take a break and catch up on some email. When I pulled up my available wireless networks, I was greeted by a very effective use of free advertising.
I've got to give them credit. Not only was this mysterious "Asian Takeout" smart enough to realize that their neighbor (the coffee shop) would be full of laptop-carrying java junkies. But they had the forethought to 1) advertise in an extremely unconventional spot, and 2) have the goodwill to offer up free wifi as well. I don't know about you, but I've got the munchies.
