As the goalless game went into its second minute of stoppage time and Brazilian midfielder Renato Augusto missed a wide open chance at goal against Iraq, barely a moan was drawn from their table.
For many who followed Brazil's opening 0-0 result against South Africa last week, a second consecutive goalless draw for its men's football team at Rio 2016 was hardly shocking.
But the fact that the Olympic hosts have failed to score a single goal on home soil against two nations who had once only dreamed of being in the same footballing conversation with Brazil is a testament to just how low things have sunk.
"This is ridiculous," said Lucas Garrido, one of the three friends from Harvard, who currently works at a private equity firm in Rio.
"I think we are not as professional as other countries, where they are investing money and hiring decent people. In Brazil it's still very amateurish. After the World Cup, it just keeps getting worse," he added.
Garrido was of course referring to Brazil's 7-1 drubbing to Germany in the semifinals of the 2014 World Cup played at home.
Since then nothing has come easy for Brazilian football, which is bad timing. The country could use a distraction from its current recession and ongoing presidential impeachment process.
The Olympic tournament was billed as Brazil's redemption in the form of a gold medal, the one major international trophy it has yet to earn. Instead, the team faces ouster unless it beats Denmark on Wednesday in Salvador.
"We lost the joy when playing," echoed Garrido's former classmate Tulio Gomez, who cited talented 2002 World Cup winners like Ronaldinho, Rivaldo and Roberto Carlos as exuding such joy. "Even when there were no goals it was fun to watch, but now I don't know ... It's boring."
So boring, in fact, that the home crowd of 60,000 in Brasilia preferred cheering for Iraq, whose only strategy was to defend while handing over 77% of possession.
"We have been a very lucky generation, I guess," lamented their friend Marcelle Goncalves. "For us this is very new."
Struggling in this manner is unnatural for every Brazilian generation since the country welcomed home its first World Cup winning squad of 1958. Ever since 17-year-old Pele led the team to victory in Sweden, Brazil has been blessed with those who have played both entertainingly and effectively.
But on the heels of dour results in last month's Copa America -- a 1-0 loss to Peru and yet another goalless draw, this time to Ecuador-- which saw Brazil's senior team crash out at the group stage, the consensus is in: Brazilian football is in crisis.
"I think this is very bad, like everybody who watched," said Carlos Alberto Torres, who captained Brazil's World Cup side of 1970, to CNN. "It is a surprise because of the competition. It is not the best level of competition, of course. We should at least score goals."
What will it take to turn around the team's fortunes?
"Ah, this is a great question," Alberto said, before pointing out that the Brazilian Football Confederation (BFC), in essence, needs a gut check.
"They think that Brazil can always produce great players because of our culture and tradition, and now this is not the case," said the 72-year-old known for scoring one of the greatest goals in World Cup history, a right-footed smash off a Pele assist for the team's fourth goal in the 1970 final against Italy.
