Sarah was already stomping down the street ahead.

Well, doing her best at stomping ahead. Some of it was a little too wobbly to be called stomping. She was feeling a very muddled kind anger and couldn't really pinpoint the reason, which just made her angrier.

She was unlikely to actually lose them, because that wasn't her intention. Mostly. (She wasn't even moving fast enough for that.) She was just being an ass in her own way.
