The only time I find it useful is when I’m driving while drinking a side I got at the fast food place I stopped at. It’s pretty easy to drive while drinking out of a straw.
Those cups in themselves are a pain. Why cant they just hand out PET bottles like you get everywhere else? (at least in europe)
hand out a reusable sport cap aswell and you have a perfect bottle without the need of
a) a straw
b) a cup
c) a lid
A bottle uses way more plastic than our flimsy plastic lids do. Paper cups are mostly paper which comes from trees which are grown just because there’s a need for paper (big carbon win).
It would be a massive step backward to use bottles instead of fountain drinks. Not to mention how much more expensive they are than a fountain drink. And there’s no way you could fill them efficiently from a fountain at the restaurant.
