At LAX, it depends on the terminal. In Bradley, the bank of GE kiosks comes before a desk. If that CBP person is busy with another passenger or a phone call, they will usually waive people through with no X. If they aren't, they will often harass GE passengers - even US citizens and LPRs.
At YYZ, they have moved to having no one sitting at the customs desk. Instead, everyone, regardless of checked bags or not, hands their receipt in and scans the BP. They usually ask "checked bags?" If you say no, they have you go by. IDK about if you do, as I don't usually check. I've seen them grilling more GE people since 1/20.

That's not my experience at YYZ lately, at all.
