I'm sitting in the lobby waiting for a blood test, typing away on my laptop.
There's a secured wireless network here. Why not an unsecured one for people like me?
What's the big deal in providing free wireless access?
The routers are dirt cheap, security's not a concern, and most people aren't going to be using it, but those who are will love it.
It'll change the nature of the experience.
What little, inexpensive things can you do to make a big impression?
