Watch the movie up to the part where the Jamal decides to stay and is annouced by the dwaft. This is the part where he shows his drawing for the 'Jamal in the Box' ride through eatery. If you look closely at his shirt right after he presents his frappacino you can clearly see the SKY logo exposed on the shirt. Then about a minute later another guy walking in in purple and red and this is where Jamal presents his SKY logo. Slip up being the logo was already exposed long before this.
