Only if you're in a hurry! The interviewer can patiently wait for the subject to become bored. Formal interviews in intimidating settings (like panel interviews for jobs) are often scheduled to be much longer than necessary just on the expectation that the first half will be nervous ice-breaking and the real insights are after everyone loosens up and is capable of acting naturally. That's probably half of "in vino veritas": drinking is an excuse to spend a few extra hours with nothing to do but chat.
