I don't know if this particular case is real, but it would totally be possible with many companies.

In large companies I've worked in, many bills are sent to the HQ front desk, but nobody there has any real idea of all the things they spend money on across their thousands of employees across offices in dozens of different countries.

And nobody wants any legal trouble, so there's a bias towards just paying.

In better-organized companies these things have to go through the local office manager who should have an overview over purchases connected to that site, and then employee-specific expenses should go through a managerial process etc... but not all office managers are that on-the-ball and if you send one that seems plausible enough and doesn't neatly fit into any of the other categories, I can still see it going through
