THE DRILLING RIG TRUCK BECAME STUCK IN A MUDDY FIELD. EMPLOYEE #1, THE DRIVER OF THE WATER TRUCK, ATTEMPTED TO PULL THE DRILLING RIG TRUCK OUT OF THE MUD. THIS ATTEMPT FAILED AS THE WATER TRUCK WHEELS SPUN. THE SUPERVISOR TOLD EMPLOYEE #1 TO GET OUT OF THE WATER TRUCK SO HE (THE SUPERVISOR) COULD REPOSITION THE WATER TRUCK AND MAKE ANOTHER ATTEMPT.
