Penguina,
It's just a case of knowing who you can swagger in front of.
e.g.
(a) The FISO, who, when your turned downwind, pointed out you were heading for the wrong runway. No swagger. (More like 'hiding').
(b) The people in the caff who didn't see this little debacle unfolding. Swagger on!
This is obviously not based on any actual experience, it never happened at Lydd, etc etc...
