Dialog 1 ruffle someone's feathers [ 人を怒らせる ]

Yukio:I asked for a cola but my waitress brought me coffee.
Angela:Sounds like she couldn't understand your Japanese accent.
Yukio:When I asked if they have soup or salad, she said, "Yes, we have a "super salad!" Argh!
Angela:Don't let her ruffle your feathers. They were honest mistakes.

Dialog 2 toe the line [ 規則にしたがう ]

Angela:It looks like we're going to have a different captain for our flight.
Yukio:Really? What happened to Mr. Nakakubosujisato?
Angela:On his last flight, he let a couple of flight attendants fly the plane for a little while.
Yukio:Ooh, that's dangerous! Well, if you don't toe the line you'll be transferred or fired.
