Isn't McD worse then? It's encouraging people to eat/drink more sugar and carbs then one should just for a chance to win. Making them more unhealthly. There is also no limit, people can (and do) buy it and chuck it away. Or eat part of it. And end of the day you have nothing "representing" what you got for your money except some more weight on the scale. The skin lasts a lot longer and is better then junk food. At least the skin is neutral, McD has a negative benefit even if it is more tangible.
