You are going to a CAA consultant. His job is to determine your fitness under the CAA regulations.
It is not a relaxed arrangement in the slightest.
Whilst the first sentence is obvious, the second is patently wrong!
Basic common sense would suggest that any good professional consultant is going to put the patient at ease. Even if that were not the case, this is an appointment with a psychiatrist and not a proctologist! Why on Earth would it be anything other than a relaxed appointment given that the patient is likely to be apprehensive in advance? In any event these are moot points as three patients have already stated it is indeed relaxed.
