Pre 9/11, I was sat in the jumps seat in the cockpit of a late evening flight LGW-MLA with Air Malta. Both crew with feet up on instrument panel. Somewhere down the west side of Italy, ATC says "Reroute via Point Bravo" [loads of those, I'm sure]. Flurry of maps, and Captain says to FO "Probably that intersection there" and winds heading knob on the autopilot.
I slightly lost confidence in flying with them after that.
