Peet's and CPK tell Open Carry customers: No guns allowed Open Carry gun advocates in the Bay Area are easy to spot. With unloaded firearms strapped to their sides, they meet at coffee shops and other places to protest exercise their right to bear arms, drawing plenty of attention from the media, cops and bystanders along the way. A group of proponents converged at a local Starbucks in November. Earlier this month, members of Bay Area Open Carry gathered at a Peet's Coffee & Tea in Livermore, triggering a 911 call. Cops responded and frisked one man during his interview with ABC7 (see video below). And last week's meeting at the Peet's in San Ramon caused quite a stir among customers who both disapproved and praised the heat-packing patrons, according to The Oakland Tribune. .. The policies didn't exactly go over well with Open Carry proponents. On an online forum, they called for boycotts of Peet's and CPK. Someone even posted a protest sign (right). Open Carry rules vary from state to state. In California, an open carrier's firearm must be unloaded and holstered. The ammo must be kept separate from the gun. Cops are allowed to inspect the weapon but cannot search for the gun's serial number. And as one recently San Jose man discovered, it is illegal to possess a gun within 1,000 feet of any public or private school. The Scavenger : Peet's and CPK tell Open Carry customers: No guns allowed i respect the right of the establishments to deny service, as i respect the rights of those to exercise their rights to bear arms. IMO, this is a negative way to exercise your rights and i believe will only bring negative reactions to gun rights.
