I have gotten thoroughly sick and tired of this conversation:

Me: I have a hearing impairment, please speak clearly.
Salesperson (SP): *continues mumbling*
Me: Sorry?
SP: *mumbles again*
Me: I'm looking for a phone that is compatible with my hearing aids, do you have live phones I can test?
SP: *looks at me like I'm a three-headed alien, and mumbles again*
Me: *puzzled, look at friend who is with me*
Friend: He said no, they don't have any activated phones, here's his card if you want to come back and buy a phone.
Me: *does not take card, and leaves store*
