Straws (drinking ones)

Paid a rare visit to McDonalds for a Filet o Fish meal yesterday. Forgot to pick up a straw, and because the restaurant was crowded decided not to go get one and just drink from the cup instead. Made me wonder why I ever get a straw in the first place, since I drink from the cup at home and it really isn't that hard. And given how many people eat at McDonalds... if even 50% of customers stopped using straws... well thats a lot of plastic.
