Topicality and Ill-fashioned fellows

In a footnote in my edition of The Man of Mode, David Wormersley refers to the "extreme topicality" of the play. While we have seen many contemporaneous allusions in plays throughout the semester - particularly as they relate to fashionable places in the city of London - references to pastimes, people, places and fashions of the moment do indeed seem extreme in Etherege's play. What makes this play more of a particular cultural moment than other plays we have read this semester, perhaps even more so than The Country Wife? How is it related to its own time? What kind of cultural capital is important in The Man of Mode in comparison with other plays?

What is the purpose of the intrusion of "four ill-fashioned fellows" smelling of tobacco and coffee houses in III.iii? Are they merely meant to highlight the gentility of the play's main characters, particularly Sir Fopling who appears in the scene, or are they acting as a kind of parody of the men about town?
