You don't want to do it like that . . .

As I passed this work area I heard one of those hanging on the outside of the fence ask, "Why are you cutting that stone, Alec?"  Or something like that.

Then all five or six of them spent the next ten minutes or so discussing the best way to do something, without much being achieved.  Meanwhile the pavement was constricted and a chicane in the street was slowing traffic markedly.
