As I said on the day, if I haven't been told of your activities where you were (i.e. being there with lawful authority and excuse), then I will ask questions
every time.
With all due respect Fred, airline staff can hardly claim they have an 'intimate' knowledge of that end of the field, hence the attention when they go there or sometimes 'stray' there.
And I think if anyone thought I was being serious about having a price to go 'spotting' with, then they obviously didn't pick up on the 'deep pockets' comment.
