It's really weird that we've normalized consuming huge amounts of what's effectively an exceptionally-sweet dessert drink with most non-fancy restaurant or fast-food meals. Shit made a lot more sense when standard serving size was like 7oz and free soda refills weren't a common thing (so: the 1950s or whenever, for the former, and before some time in the '90s, for the latter). 20+oz glasses (and 32oz "medium-size" to-go cups—JFC) and free refills pushed by servers are just nuts. That's so very much sugar.
Imagine consuming a pile of 37 Pixy Stix (sugar equivalent of 24oz of Coca Cola) to accompany a hamburger. WTF. That's plainly nasty as hell, and anyone doing that in public would rightly feel ashamed. And that's not even a large serving of soda, by modern standards.
