I'm not a fan of boycotts, so what follows is just a bit of trivia that might interest people who were insulted by Hugo Chavez's recent lunacy: CITGO is owned by the Venezuelan government.
The company is owned by PDV America, Inc., an indirect, wholly owned subsidiary of Petróleos de Venezuela, S.A., the national oil company of the Bolivarian Republic of Venezuela.
That means that if you buy gas from a CITGO station, you're directly supporting the Chavez government.
(HT: DeoDuce and reagan80.)
Even though most of the money goes to Japan, Seven-Eleven isn't completely free of CITGO's tentacles either.
And if you buy gas from any other station, you are supporting bin Laden :-)
