When I come to you for a cup of coffee and you charge me $4.30, I don't want half of the tiny glass to be foam... I want it to be no more than a centimeter, ever... It needs to be hot but not too hot, fresh, strong... You prove to me often that you shouldn't be allowed to serve coffee and certainly not for $4.30... Here is what I like. Print it out and stick it on your wall.
