The paperwork arrived at her office and she filed it away. That’s something, isn’t it? That’s something that makes her uniquely qualified.
And I expect it was a civil service worker who actually processed those applications (or licenses or whatever), mailed back any approvals with Grime's signature being “signed” by an auto-pen. The clerks likely produced periodic reports and when Grimes saw the report in her in-basket (actual physical or email inbox) with the counts she probably said “So THIS is what I've been doing, creating all these new businesses. Damn, I'm good!”.
