On my CPL course, having rec'd the mandatory "go and start up and I'll join you when you've started up etc etc" and having waited 20 minutes on the ground, I called Information with a 'lift and air taxi to remind the CFI' call.
Parking outside of his window I could see the conversation continuing inside, so I turned on the landing lights to attract attention.
Then a hand came up from inside and closed the window and blinds as the light and noise was disturbing the conversation ...
Finally, I shut down, went inside and said I was ready.
At which "go and start up and I'll etc etc"....
Rinse and Repeat.
