The deal breaker for me that caused me to miss my first meeting on purpose and never attend another was when I was beginning to teach others in the congregation ASL so they could relieve the one interpreter we had.
I was a regular attendee and she was visibly worn out.
The PO said in a text message: WE ARE NOT GOING TO NOR ARE WE PLANNING TO ESTABLISH A SIGN LANGUAGE GROUP HERE, SO WE WILL NOT BE ASKING OTHERS TO LEARN SIGN LANGUAGE.
That did it. I did not attend another meeting after that.
The one interpreter didn't have much more support from them, either. We were very frustrated that we had to clear and ask for every little thing through and from them, but they were not willing to lift a finger in support.
