You knew (or suspected) that the young man was mentally disabled. Let's face it--he was with his mom. Even the most rabid 'baggers are not going to literally growl. 
Your husband said that thing about the growling loudly enough for the mother to hear. Was that appropriate? Did he actually want her to hear, perhaps? In other words, did he feel like she wasn't controlling her child and wanted her to know that?
Imagine how that woman is burdened 24/7/365 having to take care of her son. You are thinking about your high blood pressure but what about her?
And in the other scenario, what was the point about yelling about lack of cashiers? How does that serve you or anyone else in that moment? If you really felt that it needed to be changed, why not write or call the person in charge? 
Otherwise you are just creating more negativity, which is not manifesting much Light! 
I echo the other poster--MOVE! Don't find any more excuses--just do it. Eckhart Tolle says that either we accept what is or walk away from it. Complaining is just madness, he says. Can you disagree with that? 
Take care!
