Here the man in blue crimplene accosted us once more but we patiently explained to him that he could fuck off.

Our reading
An editorial interpretation.
The narrator describes another approach from the man in blue crimplene, followed by an emphatic profane dismissal. Calling that dismissal a patient explanation supplies the comic mismatch. The manners suggested by the narration sit very neatly against the rudeness of what was actually said.
