LOL.

Let me get this right.

The Chinese Ministry of Foreign Affairs is so janky as fuck as to let any Chinese shop owner on Earth:

1. adjudicate passport renewal applications

And

2. only do it as a legally recognized foreign law enforcement entity

But it's "just, like, an old couple that also sells Fanta and whatnot."

Is that actually what you're saying? Because there's not a single African nation that would ever even allow that, and they have some loosey-goosey rules.
