Not familiar with the US experience, "wife" might give you preference, but for the UK, it's exactly my experience too, to the point of feeling guilty of just waving you through. For all the news stories of terror alerts and security, I've often found the "UK and EU" lines *unmanned*! I've had to look around to find someone, as I don't want to be chased down by an armed guard for skipping it.What passport where you on? I've seen huge differences at various Heathrow terminals for a EU passport versus a non-EU passport.
With my non-EU wife I realized that bringing her with me in the EU queue (what queue?) was much, much faster - and never any complaints from anyone there about doing that (in fact, I started doing that after we entered the US on one occasion, with her in the US queue, and me on the non-US queue, and we got a lecture for not going through the same queue, if we were travelling together - despite the signage!).
Quite often where they just glance at you and nod, they're reading demeanour, or looking for a known description of someone and it's not you.
