Zapata, do you mean like insisting on getting a readback of required items? Little things like flight levels, headings & clearances. I doubt anyone insists on word perfect phraseology. Geez, you wouldn't be referring to the American way when you say the rest of the world would you?
We're human. If you usually refer to OOD as Oodnadatta & far more often than as oscar oscar delta then it's going to slip out as the usual way occasionally.
