If the propritorer (sp?) of an establishment is offering free wi-fi, then they should limit the range of their wi-fi signal by placement of the AP.
Some important questions:
1. Did she have a web page agreement statement regarding the use of the Re-Union's WiFi network?
2. If no web page agreement statement, then were there signs or some other means of notification regarding the use of the WiFi network?
This is a dangerous precident. Now everyone will require that you purchase product(s) in order to avoid legal ensarements linked to using the "Free" WiFi.
