The point being that the Gesundheitsleiter wasn't experiencing the suffering he was visiting so casually on others.
He had come to levy fines on the restaurant owner for not obeying the Gesundheitsbefehls – health orders – of Gesundheitsfuhrer Gavin Newsome, who has been caught ignoring his own befehls – which do not apply to him, of course, since he controls the Gesundheitsleiters and AGWs who enforce the befehls.
Some of these fines were apparently issued to the restaurant owner on account of people sitting outside his restaurant, on city-owned benches situated on the city-owned sidewalk – over which the restaurant owner has no control, since it's not his property. How, he asked, is he supposed to police people sitting on public benches on public property?
The restaurant owner was using his truck to try to convey to the Gesundheitsleiter what it felt like to be prevented from working, the very thing the Gesundheitsleiter had come to make sure the restaurant owner didn't do by punishing him for trying to do.
Armed government workers arrived – to aid the Gesundheitsleiter. To make sure he was unhindered in the performance of his job.
