I'm a captain with a major airline, and I routinely monitor the flight attendants' announcements while taxiing to the gate.

Impatient passengers often stand up and attempt to dash forward before we arrive. 

Once, instead of the usual terse voice reminding people to  remain in their seats, I heard the attendant declare:

"In the history of our airline, no passenger has ever beaten the aircraft to the gate.  So, Ladies and Gentlemen, please remain seated."
