Not that what he’s saying particularly resonates, but as I suspected whoever wrote that is deliberately mangling what he said.
R’ Avigdor Miller many times said if you can’t get yourself to thank those that are doing favors/services for you then you can forget about being able to feel sincerely thankful to Hashem.
I’m not ascribing to the posted hashkafa and regarding what he said about ‘just doing their duty’, but either way R’ Miller said of course you thank the bus driver even though he’s just doing his duty. Duh.
