Ian orders the cab driver to stay where he is. Teri herself actually has no idea what he's talking about, or why he wants the cab anymore. This makes it pretty clear, incidentally, that Flo had no way of knowing they wanted the cab to stay, since Teri didn't even know. Ian says to Teri, "I want him to stay here." Teri points out that they can get another taxi. "I. Want. Him. To. Stay. Here," Ian says, just as if his wife is his four-year-old child. Flo, meanwhile, is licking her wounds over the unnecessary snarling. "You don't need to yell, that was really rude," Flo calls over to them, horribly whiny in her delivery but absolutely correct on substance. "I didn't know that was your taxi."
As Asshat walks into the mosque, Ian says to Teri again, just as patronizingly as last time, "I want him to stay here." He goes on, "When I make a decision, it's a decision. That's it." So apparently, she isn't to question him when he says something. Teri snaps back, "We're a team." No response on his part is shown. God, I cannot stand them. And don't give me editing, and don't give me "characters," and don't give me "they're probably perfectly nice in other contexts." That was just ridiculous behavior throughout that entire scene.
Back at the FloZach car, she's still unhappy. "It's not nice to yell at me like that...I'm not...he's not my..." Unable to finish her thought, Flo sighs and gets in the car. Heh. I thought that was sort of funny for some reason. But damn, that is one whiny whine she has there.
