Alex, is this meant to be a warning that you won't do something a second time? [father]: "I'm glad you're car is working now, but this is the last time I pay for your car repairs. If you're old enough to have a car, you're old enough to get a job!"

No, it’s like “Don’t talk to strangers, or you’ll get kidnapped.”

Like “Let this be the last time you...!”
