I do, it's the ice that hurts my teeth a lot without one. And without ice it's too warm again (also on the ordering machines these days you can't select without ice).

Also with alcoholic drinks eg rum colas it's easier to drink more slowly with them.

So instead of drinking more slowly and taking smaller sips we have to use a plastic device we throw away after, got it. Doesn't seem very smart to me honestly.

As I said, "almost no one needs" but your example isn't what I meant. Let's say someone with a disability that can'd use a cup.
