I once insulted an employer with this expression :).
I told them that in the past we were building sheds, and that it all went very well. But now there was a skyskraper project, and that they cannot expect us to build that in the same way. I wanted to make clear that this bigger project needed more structure to support it.
All they heard was "what??? You think we build sheds???" :D.
Nothing wrong with building sheds of course. In fact those are the most fun projects.
Of course, which is why applying grandiose judgements to the people who just choose to build sheds, is misguided in the extreme.
