Dunn Bros. is a beloved Twin Cities institution, according to the folks there: Dunn offers Wi-Fi at no cost in its coffeeshops that have the service in contrast to competitors like Caribou (SBC FreedomLink) and Starbucks (T-Mobile). Not unusual. But Dunn will take to magazines and buses promoting its free service. Once you push something like free Wi-Fi you need to ensure that all of your locations sport it.
When will Panera start THEIR free WiFi advertising campaign? They're the only ones able to really knock the "for-fee" cafe model to the ground. Such an advertising campaign has the potential to draw people away from Starbucks, and influence other restaurant chains to offer free WiFi in the future. Panera has the ability; these small chains have little influence. It's the only way to keep the SBCs and T-Mobiles out of the cafe space. They wouldn't be interested if they had to offer it for free, and there should only be a charge in amenity/home locations.
