Oh, I believe you. How unpleasant to have to paw through other peoples' garbage to separate what they could have done themselves with a little consciousness and no particular effort.
Maybe you should have someone take a photo of you, rubber gloved, sitting in the midst of egg shells, orange peels, plastic bottles, cardboard boxes, empty glass jars and actual garbage, pawing through it, looking up at the camera with a nauseous expression. Then put it on your instruction sheet on the fridge with a caption "Dear guests, Please don't make me do this!"
Most people seemed quite hip about recycling when I lived in Canada, but that was coastal BC, not Alberta.
