Semi-free Wi-Fi Service For Customers

Caribou Coffee is now offering semi-free WiFi for their customers.

"Customers will have access to free Wi-Fi during the first hour, and then will be asked to make a minimum $1.50 store purchase, about the price of a small cup of Caribou coffee, for each additional hour to receive a Wi-Fi access code."

I like this idea. Give a certain level of free service and then make sure the user is supporting such service by requiring them to make a minimal purchase. I'm not saying that this applies to libraries but it's better than charging what most chain coffeeshops and airports charge.
