Hope I didn't give the impression of ever having been treated "too harshly" by a controller (or in my case FIS guy/gal). Quite the reverse, always felt and feel well "looked after", and during one of the abovementioned mishaps, the approach controller apparently even phoned my local aerodrome (correctly guessing by my transponder code and position) and made them tell me on the R/T to please descend somewhat or buzz off. So definitely no "chastising witch-hunt"-mentality.
While we're at it: what are the potential consequences of such "minor" CAS infringements (beyond apologising on the R/T or by phone afterwards)?
