I see others are acquainted with "Dick Richard"*
Once a Dick, always a Dick, sadly. The man who refused to take a handover in a busy Approach Room because he'd been called 'Dick', and said "My name's Richard, Dick is on the other watch." I served with him on 4 separate occasions, for which I should have been awarded an MBE at least.
* A name coined by/used by the Stn Cdr at a secret Far East airfield
