Unfortunately, the embedding of the video has been disabled, so you'll have to follow the link below to see it, but here's a clip from Love Actually. What's happening here is that Harry (Alan Rickman) is buying an expensive necklace for a woman in his office. He's trying to do this quickly and quietly, because the woman is not his wife, who is shopping in the same store with him. But the jewelry counter man (Rowan Atkinson) will not be rushed with the increasingly insane gift-wrapping process.
Watch it here. It's a great comedic moment, and it's an interesting one because you're not sure who you should be rooting for here!
