Overheard at work.....
"Did you stuff it all the way in?"
Not a good sign when you have to ask.
But it can be an important question! Some years ago my hubby drove all the way to Paris (on business) because someone had not stuffed it all the way in.
A disc on the control unit of a paving machine, that is. They claimed the machine not to be working; hubby asked exactly the same thing over the phone and they assured him they did. So he hopped in a car, drove all the way only to find out they hadn't stuffed it all the way in.
With one movement of his thumb he "repaired" the whole, huge machine.
