That was my first thought as well, but it's not pointless, so I don't think it belongs in this thread.

It... just makes sense?

Eats bushes, and leaves

I'll go a step further.

I regularly use comma's commas where they don't belong, just to reflect my speech patterns IRL.

I’m so irritated because I allowed myself to get out of the habit. I worked at a place for eight years where the marketing department insisted on not using it as part of their style guidelines and we were all supposed to follow suit. I disagreed in principle (and actually I’m pretty sure the marketing director agreed with me, but was overruled by the executive director) but still had to adapt, and I guess eight years was long enough that I don’t automatically put it in anymore and it pisses me off that I now have to think about it.

Woah, woah, woah. Let's not get too carried way here. Some things we just shouldn't talk about.

New find.

I also realised that it could actually be useful in this Grammarly page. The last section "Oxford comma confusion".
