An environmentalist Aussie goes to Safeway and buys some organic food and goes to the check out counter. The checkout clerks asks him what kind of bags would he prefer.
“Paper or plastic”
“Paper, please. Plastic is not environment friendly.”
The question of paper and plastic was raised again when he asked the gentleman how he would prefer to pay. “Paper”. He said and took out a note of 50 dollars.
The clerk takes it “polypropylene polymer, so you are not so averse to plastic after all.”
