I think that all our AME's are a bit miffed at having their income from medical examinations significantly reduced by the new rules, they are bound to try and increase their income a bit if they can get away with it!
P.P.
I think that's a little unfair PP. Most AME's are PPL holders themselves and are hip to the financial problems which most of us instructors and recreational pilots endure whilst pursuing our pleasures and goals. Indeed, my AME (who incidentally is a retired GP but very keen flyer) always gives me a discounted price at renewal which is absolutely fantastic of him.
VFE.
