(Vancouver, WA)  --  Two men are facing charges after allegedly attacking a pot shop employee with a bong while robbing the joint.  The Clark County Sheriff's Office arrested Jose Vega Salazar Wednesday and Cruz Dominguez last month for the incident in late November.  Police say the two entered the store with their own bong and asked the clerk to see a similar bong being sold at the store.  When the clerk handed them the bong, they allegedly grabbed it and ran out of the store.  Police say the clerk chased them, prompting the suspects to hit him over the head with the bong they'd brought into the store several times and then kick and punch him after he fell to the ground.  They're facing charges of first-degree robbery.
