The World Cup-winning coach had been speaking to the media after the Selecao's 2-2 draw with Chile in an open and exciting friendly clash on Wednesday. The press conference was drawing to a close, but Scolari made a swift exit after being asked if his future hinged on a successful defense of Brazil's Confederations Cup crown.
"No comment; this is a joke," the former Chelsea boss said curtly before storming out.
Before his impromptu exit, Scolari has spoke optimistically about his side's hopes of winning this year's tournament, which will be held on home soil, claiming that the country's fans would see a far more cohesive performance than the one they had mustered against Chile.
"They can expect a better trained and better prepared side," Scolari said. "At the Confederations Cup, we will have two friendlies beforehand and the benefit of 10-15 days of training.
"For this game, we did not have the time required for the integration of the players who were chosen."
Meanwhile, Scolari refused to be drawn on the ongoing concerns about the readiness of Brazil's stadia for next year's World Cup.
"I don't know how all the venues are doing," he said. "Only the government can answer that question."
Scolari led the Selecao to World Cup glory in Japan and South Korea in 2002 but is yet to taste victory in his return to the hotseat having been re-appointed for a second stint at the end of 2012.
