Three checks is 'significant' action and would warrant a Floor Call if the Dealer or another Player insists. If no one objects to allowing Husband to act, then we can move on as it is an option the Floor does have .. but we're probably much better off allowing the Floor to make that decision.

It's probably a stretch that they would work out an OOT Action scenario in the car, but you never know. GL

As others have already said,

1. Take your case to the floors and shift manager, If needed can even go up to poker manager. But this works best if you build a very solid, more than one or two time case

2. Try to get other regs/pros to speak up, speak to mgmt and even leave games (en mass)

3. If you have done the above, nothing has happened AND if you want to ensure many right or wrong see you as a d1ck, just politely ask them when they sit down if they are still playing from the same bank roll. Let the table know the history, etc. Now realize doing this will not endear you with room mgmt. Might lead to all three of you you getting a ban. So consider possible ramifications before you proceed.
