It's just one of the many things us poor instructors get no credit for when people walk in off the street and expect to go flying, you normally only get a short amount of time to brief them before getting airborne with a complete stranger who might have any number of personnel or mental health issue or maybe was out the lash the night before and you are expected to just cope with what ever they throw at you all for £45 an hour
.
It would be nice if those that fly and have never done any instruction could stop looking done their noses at flying instructors just because they happen to be flying something bigger that day
