Regarding my disgust against people using styrofoam cups outside of plastic cups. 

I was running low,  energy wise,  and so I figured since I had Lactaid (I'm intolerant to more things than one) with me  I'll get a coffee.  So, I go inside wait in line finally get up there, and she makes it wrong.   I couldn't be mad, because you just have to expect that to happen.  Then she asks me if I want a styrofoam cup for the outside of my plastic cup.  I know I must have made quite the grimmace because I saw my reflection in her reaction to my silent disgust. Then I couldn't help but feel bad.  It's not her fault she serves wasteful assholes, but then again I suppose that she is an enabler.
