When the try to sneak in the restaurant luke is in the middle but when the scene changes he is now on the left and jessie is in the middle.
When jessie picks up the box to read the shipping label it is clearly visible but when luke looks at the box there is no shipping label on it at all.
When jessie sits down at the table bertram is holding a white sheet of paper but in the next scene it is at the corner of the table.
