What a great idea. There is lots to be learned from all cultures, and this is one that you hardly ever see. I enjoyed this.
Wow-that's really something. How wonderful to afford deaf people the opportunity to work in an environment where all of their co-workers are in the same boat as they are as far as not being able to hear. I can only imagine how I'd screw the sign language up-God only KNOWS what I'd be ordering for myself!
