Indeed. I was at game with my Father...I can't remember who we were playing, but I was like 10 or 11 years old. A group of guys in front of us sparked up a joint and began passing it around. My Father is a "live and let live" kind of guy, so he didn't say anything.
Well, one of the guys turned around, and with a smile on his face, said "here kid, want a hit?". My Father grabbed the joint, dropped it on the ground, and smooshed it with his boot. The guy did not say a word (my father is a pretty large and intimidating guy), and my Father calmly went back to watching the game.
