Helpful stacker
When I was working on the line, it was standard practice for all pressure refuellers to carry open-line nozzles for use on aircraft not fitted for pressure refuelling. As you pointed out, they were easily fitted to the pressure coupling when required and stored in a 'clean' box when not in use.
Maybe the "modern" Air Force doesn't think that such a useful tool is necessary any more.
Even so, somebody deserves to have his a**e severly kicked for making such a basic error of judgement when ordering the replacement refuellers.
