Phantom:
Not only for walk around, but when you walk through the cabin and when you go the washroom,cap "should be" FIRMLY planted.
This remind me a story i heard once: when one of our "fellow scared" colleague when to the washroom with his cap(apparently not firmly planted enough..
),While he was releasing from a physiological need..his cap felt down inside..guess where..
Everybody including the F/O were wondering where the cpt disappeared while he was rinsing his cap under the tap for "hours" inside the toilet..
