Back in the day I often came into contact with Army Warrant Officers including 'The' Conductor. Sometimes there was a bit of 'my appointment trumps yours' etc, mostly in good humour. My usual response was that we all had a similar certificate signed by the Secretary of State and that as far as I was concerned one set of gallopers equals another, no matter how large or elaborate.
As a WO I was once described by a US Army Lt as an officer who worked!
