Oh the WiFi threat.... have you ever used a WiFi in a coffeeshop? Do you think the owners of coffeeshop are focused on serving food or hacking computers? In most places I have been, knowing how to restart the router when it fails is the limit of the technological understanding of the people working there. They just get the router from the ISP and nothing more, the idea that they will rent additional/more expensive equipment just to hack the 10 people a day that use wifi there for a 1-2$ profit, is just ridiculous, especially since it will open them to being sued for computer crimes and/or copyright infringement.

A threat of a security camera recording your bank details while you enter them is more realistic.

And why should anyone that cares about his security use open WiFi at all? Now days everybody has a smartphone with data plan and tethering ability.
