I was perusing the bong collection in one of the souvenir stores on Fremont and casually asked the sales dude if they also sold screens. Dude went ballistic! "No, selling screens is a felony in the state of Nevada" I answered, "So, selling bongs is legal but selling screens is not." He replied, "These are not bongs. They are for tobacco." I laughed. "I'm old, but I am not an idiot. We both know what they are. I want to know if you sell screens." Dude, getting belligerent and sarcastic: "Marijuana possession is a felony in the state of Nevada." Me, calmly: "So is possession of drug paraphanalia, which is what these are." Him: "Sir, would you please leave the premises." Me: "I suppose it would be pointless to ask about rolling papers." Him: "Sir, please leave the premises or I will have security remove you." Me, over the shoulder while walking away: "Asshole."
