I recall with fondness a 'Management' brief in BrainCrank, moons ago, attesting to the huge improvements anticipated with a "New Computer" at BA (BEA/BOAC).
Management droned on interminably highlighting the advantages, 65% less input here, 70% less work there, savings over 80% etc.etc
.
A grizzled old Flight Engineer in front of me kept putting his hand up seeking a question and was irritably ignored by the burbling speaker.
Eventually the Engineer managed a response and said. " Do I understand that buying this computer will reduce workloads by over 80% Plus?"
"Yes, Yes" replied management, clearly upset that someone had not appreciated his prolonged explanation
" Well", said the Engineer " My question is Why did we not buy Two!!
Meeting concluded with endless hilarity by all bar one!
