[They managed to make it taste worse?! That’s quite the feat.]
Yeah, no kidding.
[It has a nasty aftertaste]
And aspartame doesn’t? (you didn’t mention that - I’m just saying)
That’s actually one of my thoughts that didn’t make the post. Aspartame has a nasty aftertaste. For that matter Pepsi has a nasty aftertaste. I think what they really mean is it has a nasty aftertaste they haven’t gotten used to yet.
