I believe that Jessamy reflects the more gutteral high British society ways more so than a servant would. He speaks with Jonathan about the theater and makes fun of him when he does not realize that it was in fact the theater. It is a clear distiction of values that show up between Jonathan and Jessamy that show how the difference of society can overide such qualities as modesty and simplicity. The second set of characters are Dimple and Col. Manly. Each being very distinct and unique in the roles of this play.
Dimple is a high society rogue with a gambling problem.
Manly is a respectable patriot with a deep love for America. Dimple uses all the coys and niceties of a high society man and Manly portrays the perfect gentleman. Yet Dimple is only concerned with the luxuries of life. Many in that time period were swept away by the fashions of that particular era and only concerned with the luxuries that could be afforded, or in Dimple's case, not afforded. While Dimple is the exact copy of a run of the mill highly social Britian.
