The very thing your H and ow did is my D18's biggest fear. She also works as a cashier. She made it clear to her Dad from the very beginning that she had no interest in meeting ow. So far he has respected her wishes. She has said she doesn't know how she would react if he came through her line with the ow. Just the thought makes her ill.
Has your D told her Dad that she felt uncomfortable to have them come through her line?
MLCer's are extremely selfish and insensitive. They could care less or maybe incapable of taking anyone else's feelings into consideration.
It's possible your H's change in demeanor (again) had to do with his visit to the L. The L probably fired him up over the agreement. If you don't want to meet over the SA with your H tell him to tell his L to send the proposed problems to your L. Let the L's hash it out and deal with it.
