The thing is, though, once you're in the back room, they can fairly quickly determine if you were lying, and if you did lie, that itself will be held against you. Unless you have a very good explanation for why you lied—and do a lot of groveling—just the lie can be enough to deny entrance (even if the truth is innocuous).

Explaining a non-lie can be annoying as well, but not having lied is a much better position to start from.

During the second interview in the back room it was fully explained why my friend was there. The woman in charge then told her "It doesn't really matter what you tell me now anyway, I'm going to base it off what you said the first time around." Even after I got to explain the thing again on the phone to the woman later she said if that's the case she made a mistake but there was nothing she could do about it at that point as she "just stamped the paperwork so no reversing it now."
