actually, used to work with a deaf guy here.
*** steve was an ahole tho, but spoke english well.
eventually got fired because he refused to follow supervisor, challenging him, using his disability to get away with stuff, almost getting in a fist fight... twice, and co-owner caught him screwing up on his phone for 10 mins non stop. she just stood there waiting for him to notice.....
you could say, he didn't heard it coming~ :v
(he used a hearing aid)
The school i went too had support for the hearing impaired. It was either attend my school or go to a "Special school" for the disabled. So i'm relatively used to teachers using sign and sign language around me. All of them spoke well enough, understandable, and what they couldn't convey well they would often sign anways. \o/
Some of them spoke better than i do. xD
