Many, many years ago at Manch, a "resident" and competent PPL took the wise move of submitting a flight plan for his land-away. For however and whatever reason, the controller under supervision (working towards his Tower validation and, before you ask,
Chevvron, it wasn't me) read him a SID for his clearance. Well into the TMA, the aforesaid PPL decided he was getting too close to clag for comfort and reported that he wasn't instrument rated. The situation was quickly recovered and no harm done.
Perhaps sometimes one can sound too profesional on the RTF.
