RAF Station, Germany, Cold War days.
Telephone call to the Officers' Mess, answered by the SDO:
Caller - 'hello, can I speak with the Station Commander, please. This is Air Chief Marshall X'
SDO - Pull the other one'
Caller - 'This is ACM X'
SDO - 'F**k off, Noddy' - puts phone down.
Next day, Harry's office, SDO ordered to London for 'Interview without coffee' in ACMs office. Arrives the next day at 0830 in No 1's, and waits in ACM's outer office ... all day. Finally at the end of the day, gets the summons, marches into office. After 5 minutes' of SDO standing to attention, ACM looks up from his dek, says 'F**k off, Noddy', carries on working. End of interview.
