We all do it. As do our children. When you go somewhere, especially to work, you hunt out the free WIFI like a person possessed. Getting online as soon as possible gets you reconnected to both social media and work systems.
However, in general, we never think about how “open and insecure” these WIFI networks are. We never ask the provider (Coffee house, airport, even our local Clarks shoe shop) what security practices and systems they have set up to protect you.
