I'm staying with some friends and all of their spoons are this ridiculous shape that is clearly designed for the mouth of someone like Steven Tyler. I may have to reconsider our friendship.
Some soup spoons are indeed oblong like a tablespoon. But because there isn't anything in that etsy photo above to provide context, you might miss that the heads of those spoons are most likely much larger than that of a tablespoon. Sure, they're just as oval-shaped as what OP expects, but they're also just as wide as the round spoon in the OP. Meaning they require just as Steven Tyler of a mouth to successfully misuse as a round soup spoon.
You put a spoon that big in a sugar bowl and drop it in your tea and you'll have the kind of crazily sweet iced tea they have in the American South except hot.
I bought cutlery a few years ago and decided to get exactly what I wanted, not what was standard, and I not only ended up with golden-colored, wood handled cutlery that everyone else thought was hideous, I only got fully round spoons, in both teaspoon size and standard soup spoon size.
I loved that cutlery. My old roommate… gratefully tolerates it. I just have a giant mouth and never realized it could be an issue, but even the small ones were surprisingly unpopular
Here's a wild thought: You can choose to pick up only a little bit of sugar. No one's forcing you to fill up the whole spoon like a digger on a JCB lol.
