Interesting...I never saw something like this here. But for most of the times having free Wi-Fi or not doesn't matter here because for quite an amount of places their free Wi-Fi does not really work :3

It's actually a little funny when you think of it - if we have something that advantages females instead of males, no one will shout (except for a few like you who knows what is going on). If the other side happened like "Free WiFi for males" then probably it's going on CNN, although both cases can be considered as serious discrimination.

Now thinking about it, if you posted this on Facebook you might accidentally ignite the 3rd World War :3 The sign is still there for a reason, and we have a long way to go before most people become sane :)
