3 adjectives to describe perks

The "deadhead" perks itself in your face at every turn, in flunkeyish gratitude for invitations, drinks, dinners, and free passes,from "the gentlemanly Lord Napier," down to "intelligent and gentlemanly" railway-conductors, "gentlemanly and attentive" hotel-clerks, "gracious, gentlemanly, and gallant" tavern-keepers, and their "lovely and accomplished brides."

And, should my plea for reasonable perks (Barely four thousand pounds) be flatly quashed; Should kind Sir ALF, Commissioner of Works, Be forced to leave me liftless and half-washed; Then for these homely needs of which I speak, Content with my old pittance from the nation, In Grosvenor Square (or Berkeley) I will seek Private accommodation.

" "One of the better perks," Tom admitted.
