Require paid WiFi be distinguishable.

Currently there is a standard symbol that is used to show there is a WiFi network available in a building or location. The only issue with this is that you are not able to tell if this WiFi hotspot requires payment to use without attempting to log onto the network.
I propose that the symbol be altered to display when a WiFi network is a paid network. Currently the symbol is a series of 3 curved lines emanating from one point. I propose that this symbol be altered by simply overlaying a dollar sign ($) over the existing symbol. This will greatly help consumers, and prevent businesses from abusing the idea of free internet.
