My second favorite tex mex restaurant (Hacienda) also blocks INGO from their public wifi. I posted a picture to their corporate facebook page of my ipad with their "inappropriate content: weapons" block screen next to my beer and plate of food sitting on the bar with the comment "I'm old enough and responsible enough to sit here in your bar and drink a beer, but heaven forbid I look at anything weapons related. Seriously?" No response.
I can understand porn and such that could offend neighboring diners who might glance at my screen, but INGO? Srsly?
I hear you brother, it's down right stupid.
