Corrected entry: When De Nero is asking the "Sheik" questions in Arabic, one of the FBI undercover guys rescues him by acting drunk and interrupting the meeting. At that point they whisk the Sheik away. In a following scene, he's still at the table.

Correction: I have watched the scene twice now and there is no evidence of anyone leaving the table when the FBI guy interrupts.
