I've never had a problem with a pax yet. Although having an SRG inspector in the family as caused one or two ATSUs along the way to have a problem!
It's kind of funny the way none pilots have such different perceptions of flying! For example "are all pilots geeks!" I'm trying to pursuade a fantastic young lady to come and aviate with me. She's a bit cautious of flying, and I learnt that people like that need to convince themselves they want to come, rather than getting bullied into it..(any tips on that would be much appreciated!). However, she's off white water rafting in a month or two! Naturally, I was mock offended that she would do that but be scared to get in an airplane! Her response made me laugh though.."I really couldn't get into aerial EXTREME SPORTS"???? Now I don't know about you, but going to Guernsey for Fish and Chips never seemed like an extreme sport to me!!
