Being late for Met Brief .. Not a good idea for either side.
IIRC, a thread on here yonks ago mentioned an exchange between a UK Fighter Controller and a flight of America's finest .. which went something along the lines of
"FC123, this is Assh0le flight checking in"
FC "Err, say reason for choice of callsign"
"Late for Met brief"
No idea if it's actually true but wouldn't you love it to be!
