And never ask to see a CFI without an appointment!
Come of the grass Charlie Foxtrot etc If the CFI (you are presumably referring to yourself) is that remote as to demand students make a bloody appointment then steer clear of that operator. The flying school wants your money and it is your money that pays the CFI. CFI's may sport four gold bars, real dark sunnies over their head and a big watch and even bigger wings but deep down they are just humble folks - NOT.
