Those drums in the picture are really badly filled as well, I’d have rejected them if they’d turned up to the warehouse looking like that back when I was doing QA.
I had a colonoscopy years ago when I was engaged to my now-wife, and when I woke up from the anaesthesia I just babbled about how much I loved her. At no point did I come remotely close to doing a Nazi salute.
