an outbreak of clue

An outbreak of clue here in North Beach. Caffe Roma, (that’s Columbus and Union, San Franciscans) has free Wifi after Tony, the owner, was approached by Surf’n’Sip to start a pay-for service. Hmm, he thought, I have DSL anyway, what if I just bought an airport and gave it away? Result – tables filled with laptop users, and an increase in the sale of coffee, sandwiches, and ice cream. He’s a happy man.

For $30 – $50/month plus the hardware cost ($200), why don’t more coffee shops, etc. do this?
