Imagine if establishments that have a TV on (pizza places, chinese resturants, bars, waiting rooms, hostpitals, airports, train stations, etc) tried to charge customers who watched the TV to pay for the cost of the TV and cable. This is what pay-for-WiFi is trying to do.

It is better to just give it away, and eat the cost as part of your "advertising". This is true of almost any service where the cost of billing is far greater than the cost of service. For instance, airports don't charge me for the electric I use when I plug my laptop into a wall socket. Resturants don't charge me for a glass of water with my meal.

And if you already have the data lines installed for your business use, why not spring for the $50 to offer WiFi to your customers? Now by all means, firewall off your corporate machines from the data network you offer the public. But don't try and charge them for it.
