Tell the owner there's an obesity epidemic - drop the Skyhawks and get Skylanes.
Seriously though, what always drove me crazy was the DPE is a Cessna 152 that said "put my weight down as 160" during the W&B portion of the private pilot checkride. Yeah, right chubby.
There's very few examiner/applicant combinations that can takeoff with legal fuel and remain within W&B on a checkride in a 152, and yet it happens frequently. Double standard?
