She's late to something

The cop walked up to the car and gestured for Rachel to roll her window down. Rachel was late for her brother's piano recital, so rolled her window down only halfway.

"Good afternoon, miss, may I have your license and registration?" the cop asked with a smile.

"What. Is it?" she asked curtly and rudely as she produced her items.

"Well, ma'am, I just wanted to let you know that your taillight is busted, and-"

"You pulled me over over a stupid taillight?" Rachel asked indignantly, "I have a piano recital to get to!"

"Miss," the cop started cooling to Rachel's attitude, "it's not just a taillight. People behind you need to see you at night, and if the taillight isn't working you can get in a crash. I'll let you off with a warning but you need to get it fixed. If your brother's at the Royal Theatre there's an AutoZone you can buy them at," the trooper gave Rachel her documents back.

"Fine, whatever," Rachel started picking the worst dialog options, "am I being detained?"
