People who throw cigarette butts on the ground. Throw a lit one down, and I can't control myself.
People who carry on whole important conversations on their cellphones in public restrooms. Recently I overheard a woman obviously talking to her doctor about an upcoming appointment, symptoms, prescriptions, etc. I really tried to come up with something great to yell from my stall, but I couldn't. Maybe next time...
Oh hell. I give up trying to embed it. Any help?
