I suspect that these colleagues he speaks of do have some grasp of English, otherwise how would they get a job in the first place? I would guess that they speak it with thick accents and poor grammar and syntax i.e. not up to a standard that Mr. Osophy finds acceptable. It would appear that he lacks a complete grasp of the language too, even though it is probably much greater than theirs, but no, I did not know what he meant when he first talked of 'samolians' and 'napalians'; it took a while to work out he meant Somali and Nepali. Those aren't typing errors, since he repeated them.
