On the plane, once the flight takes off, the passengers would order, then the item would show over the passenger's heads. And the payer would get score once who gets and delivers the right item to the ones. Item got by the air hostess, which would show on the right item column. Once you want to cancel the item, just click the item image, then the one lost. After the passenger ordered, time clock animation would show on the side, the red line in the clock means patience if the player did not serve the right item, the red line will drop off until turn into white line then the passenger would be angry, then the score of the player would be deducted. Remember this and good luck!
