Maybe the host does not care about it and prefers a very loose get together rather than a semi serious one. If that bothers you too much, and the host won't take action, you must either eat it or find another game. I would not tolerate this constantly at my home game and would never do it myself, but it is also possible that your host and the couple really don't see that they are doing anything questionable. Peoples honest ignorance of poker etiquette is quite astounding.
There's much longer discussions about the merits of sending money from one stack to another when it means busting a player in a penny-ante game (or a game of any stakes, for that matter). And, if you're going to allow that, those two people GETTING head's up and then checking it down presents exactly the same situation. [If we can pass the chips back and forth, all pots ARE checked down, right?]
If you want to play serious poker, this might not be the game for you.
The husband and wife engaging in this behavior doesn't necessarily
mean that they're soft playing - at least not in a manner that's disruptive to the game - but it doesn't certainly change
The overall health of the game may be better with their playing like that.
...or it might not. Hard to tell from where I sit.
