Offering rides
If anyone shows any interest or enthusiasm and I have the time then I make a point of offering a trip. We discuss what they want to get out of the trip and I try and oblige. This generally means upside-down, looping & swooping time.
Those that ask for a ride fall into two camps a) those who are reticent to do so or ask on behalf of a friend b) those that assume because I've taken X up, they have a God-given right!
Both of these tend to happen in the pub or at social events, ie - away from the aeroplane and then arrangements have to be made. I've learned over the years to deploy the three strike rule - I offer three different opporunities to come flying and if they fail to meet any of them then they have forfeited the offer.
I won't take payment for fuel but am occasionally at a later date unexpectedly receive a gift. In the past, I've had gifts of alcohol, venison and just a few months ago, 3 tonnes of barley-straw!
The trick SDOF is to catch me in the right frame of mind at an aerodrome with my aeroplane!
