What should I expect from “free wireless Internet service”?
Your boyfriend is correct. “Wireless Internet service” is just that — a “service” through which you can connect your laptop computer to the Internet. If they provide other means of accessing the Internet, they will tell you that specifically, which might be a computer in their business center or at a kiosk in the lobby. But interpreting “wireless Internet service” to mean that they provide you with a computer is going a bit too far.
