I was out on my Saturday drive, just finished visiting my and decided to get some gas before I made it home. I pulled into my local grocery store where there was a line of cars waiting to pump their gas (this wasn't typical, but it was for this day considering it was the last day for the discount on gas and everyone was taking advantage of it). Anyway, i was sitting in the line and I was the next car in line to pump his gas, and the car that was directly parallel to me on deck for the other pump was sitting in his car smoking a cigarette. I watched him for a second, (uncomprehending my 'are you serious' face), but he didn't see this; and as his turn to pump gas was within moments, he throws the butt out the window and moves his car forward. I watched it there for about 3 seconds, still burning, an obvious fire hazard and even though there were multiple people standing around they did absolutely nothing about it. I then made the decision to get out of my car, walk over, and stomp it out; at least I thought it was the right thing to do. I start walking back to my car, and the guy who threw the cigarette out initially spoke to me, "what do you have against cigarettes kid?" He didn't say kid like he was serious, considering I look older than I actually am, he said it like I was naive and didn't know what I was missing. I told him something along the lines of "not only do they give free lung cancer, but could've well been the negligent cause of death for everyone here." He snarled at me, but tried to make it discrete, and went back to pumping gas while saying "whatever" under his breath. It never fails to present itself whenever possible; the intelligence of the human race.
