Actually
Speaking as a regulator person, some bend over for the kicking, say thank you sir, (in accordance with the APS Code of Conduct - which was obviously written by the UN) and then get obstructive to get you back.
Others tell you to "get stuffed" and pre-empt your Ministerial by telling the Minister you are "a bunch of unhelpful d!ckheads".
However there are those in industry (and it doesn't matter which one) who push a hard case but always act with honour and integrity.
Guess who gets my attention and best meeting times
