MS Encarta Dictionary suggests this is a snazzy (if somewhat archaic) term...altogether not inappropriate for many of your regulars, I would think.

toff [ tof ] (plural toffs)
nounU.K. upper-class person: somebody who is rich or upper-class, especially somebody who is also smartly dressed ( informal )

[Mid-19th century. Origin uncertain: probably a variant of tuft , a golden plume worn by titled students at Oxford and Cambridge.]

(BTW, it would be far from my nature to keep my mouth shut for more than a day...let alone 30-40 years) ;-)
