I would add straws themselves. People always complain about the paper straws that are ass, because they are. But straws themselves are. I don't think i ever drank anything and thought: you know what would make this drink better? A straw.
Same for nearly every situation except when I am driving. Hate getting them at restaurants for any drink but on the road sometimes handy.
I find it a bit funny though. I suspect that plastic lid on a drink contains 5 times the amount of plastic contained in a straw. If you get one of those large convenience store drinks, the plastic cup and lid likely contains the equivalence of 50 straws. While it is good to reduce consumption all around, I find straws are mostly just signaling. Go to a dump and you likely will be hard pressed to find a single straw but you will see tons of plastic.
