Don't Disturb the Driver

I was back in a marshrutka today. And I was most amused by the signs posted inside:
Моля не говорете по телефона, пречите на водача. (Translation: Please don't talk on the phone; you're disturbing the driver.) In the meantime, the driver would proceed to talk on his phone all he wants.
How about "The driver's constant complaining on the phone to his colleagues about traffic jams (not to mention his smoking) disturbs the passengers"? I'd like to see that sign posted somewhere.
