Consider this quote from Glengarry GlenRoss (1984)
"Patel?!?! Ravadahm Patel?!?! ....Patel? Fuck you. Fuckin' Shiva handed him a million dollars, told him sign the deal, he wouldn't sign. And Vishnu, too into the bargain. "
and then check out this report from the BBC (2009)
Meet the Patels: There are 50 Patel multi-millionaires and 500 millionaires on the Britain's annual Rich List, a level of success partly attributable to community solidarity.
