As the approach was visual, I pulled out a VFR map to check some of the reporting points. At this, he again became very agitated and said "I THOUGHT YOU SAID YOU KNEW THE WAY!"
Haha, similar thing for me.
On a regular run, with a regular passenger. Dodging some summertime storms and nicely off-track. ATC had us track via a different waypoint as it was going to make their life easier with traffic separation.
I was training one of our new guys and plugging in the waypoint (we are IFR) I get the en-route chart out to cross-check its details, lat/long etc to ensure we are tracking to where we want to go, also being off our intended track and about to descend, we needed a new Lowest Safe- all gathered from the chart.
After landing the regular pax said "i got worried we were lost when you had the map out pointing to things!!!".
I had a chuckle.
