Considering their crappy soup costs $12 in a bread "boule", this is a non-issue for me.
Why can't they just say BOWL??
Because the type of bread it's served in is called a boule. It's French.
And you can be damn sure that if I owned a restaurant and provided my customers with free wi-fi I would damn sure block sites on MY wi-fi that I thought might drive away other customers if they saw someone at the next table viewing them.
Think about it, If one of the moonbats that generally frequents Panera looks to his left and sees someone looking at an EVIL gun on gunbroker or some other site it might upset them and cause them to leave. If they leave I lose business. If I owned a Panera I'd venture to say more of my customers are anti-gun than pro-gun. Therefore I'd lose more business by keeping the gun sites, porn sites, etc. available than I would by blocking them.
It seems like a normal business decision to me, and if people don't like it they have every right not to patronize the business anymore. Good old free market.
