It is very annoying when the petrol gauge warning light, or other similarly important detail on the dashboard, is right behind your thumbs in your preferred driving position.
At South Bristol crematorium the button to descend the catafalque is out of your eyesight once you are standing at the lectern. I felt for the button as I read the committal and found two. I had to manouevre myself back until I could see the first three letters on the label c...a... t... so I pressed it and all was well. Away went the coffin. The other button turns the lights off. Commit the body for cremation and plunge the service leader into darkness; only slightly less bad than running out of petrol on the motorway eh?
