Susan I've nothing to add to all of the sound advice you've already gotten on here.
I would like to say that you're very impressive in terms of your attitude and outlook and I wouldn't be in the least bit concerned for you.
As you were well aware yourself the Credit union Mgr was an odious little creature, unsuccessfully trying to condescend to you while railroading you into buying services on ridiculous pretexts just to make his figures look a little better.
I hope your husband makes a full recovery in the near term and wishing you and your family all the best for the future.
