"Too bad. It's for the chirren. We'd like to care but we don't. Please pull over to the side and wait in line."
Yeah, that's the part I don't care for. If they want to run a drug dog by my car when I get pulled over for speeding, then they better have it done by the time my speeding ticket is written. I'd give them 10 minutes to check my license, run my plates, and write my ticket.
