Living here, I've only notice one sign--on the front door of a government building--it just says "No firearms. Law enforcement excluded." Haven't seen any otherwise, but I'm guessing if your friends say so, the signs are there. I guess some business owners have decided they don't want any guns on their property, which is well within their rights. Then I just decide I don't want to do business with them!
It is within the law for a business to prohibit firearms if they desire and it is punishable to violate their desire. I just haven't seen those signs on a private business--I guess because I don't drink!
