I love this quote from "Free hot spots pay dividends."

In fact, Shaich considers free Wi-Fi to be such an essential marketing tool that he dismisses any discussion of ROI. "What is the ROI on a bathroom?" asked Shaich, pointing out that the day of pay restrooms in restaurants has long since passed.

On most mornings, I pick-up my venti half-caf at my local Starbucks. I wish they offered free wi-fi because I don't travel enough to justify spending $30 a month for T-Mobile's Wi-Fi service.
