I had this experience with the WiFi network at Shake Shack recently. The server message said Freerepublic is “inappropriate” content. I tried to find a way to contact their network admin, but gave up, they make it very difficult to find anyone.
“Inappropriate content”
I bet but I guess they would have some fag lesbo propaganda displayed if available.
Posting on Yelp or their FB might get their attention.
Send an email to their publicist.
The obvious answer is “make it impossible for them to find you!” I would forego the best meal on the planet if it was served to me by some RAT a$$hole-run business that thinks they have a right to limit what I can get through their WiFi network. So for the cheap a$$ed $hit food served at these places, what's the problem? They are like the NFL, they are unnecessary. Don't give RATs any of your money. They just use it against you.
