Involve yourself in the situation.

"Hey!" you shout.

You immediately can tell that nothing changes, so you continue. Finally, you decide to literally start shaking the cage.

THIS gets their attention.

"I don't think that you should be yelling at the woman like that!" you shout to the pair, pointing a finger in case it's not obvious who you're referring to.

The man appears to increase his anger, which is NOW directed at YOU. However, you can see over his shoulder that Anna is laughing.

You'd heard it said that a lot of girls are attracted to a guy with a sense of humor, so you enter the cage, and begin your approach.

"I'm serious!" you continue. "My father taught me that a man should NEVER raise his voice to a woman in anger."

Anna continues to laugh, but SHE now has raised a finger.

"Relax; He's just my Coach," she confirms.

"Oh," you say. "Then I'm in the right place. You CERTAINLY shouldn't be treated that way by a man in a position of authority."

It seems that the Coach switches to a different language. However, it doesn't matter what he said, as he has thrown up his hands, and walked out of the playing area.
