The new breed of Warrant Officers do care and expect to be saluted.
One cares little what they expect ... only what they deserve! If they 'expect' to be saluted do they 'expect' themselves to return it in the S,S,SH manner in which it might have been presented.
Nah, thought not. This door swings both ways!
BTW, I was exceedingly proud of Her Majesty's Warrant which was bestowed upon me and never begrudged saluting anyone who held Her Majesty's commission.
Which not many septics do!
