Congratulations!
He could have saved the congratulations for the car, but where’s the fun in that? Picking someone up at the airport is a significant responsibility, and with great responsibility comes great power (yes, we know it’s the other way around).

This sign likely serves as a joke, and it’s pretty good, assuming his mother (or father?) has a good sense of humor. This sign turned a few heads at the terminal, especially when his parent finally arrived.
