I dunno.
I've used drive-through windows before--not often, but a few times.
When one drives up, one should carefully watch the thing; there's something that gives a clue one is being asked for his order. I'm not sure what it is; some sort of movement or light or tremor.
Really.
After which I sense my order is being requested, I give it, and repeat it a second time.
Somewhere along the line, I mention that I'm deaf.
After repeating the order a second time, I drive up to the window, and voila! my order is ready, correct in every detail.
It's never not worked.
The key here being that you don't have a victim mentality. Some folks just want everyone to pay for their disability...they are mad and someone's gonna pay.
The mentality is all wrong. It is implied that the obvious, or named, disability must come before the less obvious and unnamed disability.
The woman is limited. She cannot hear. The person on the other end of the drive-thru communication device is limited. He does not know how to cope in a situation where the person in the drive-thru cannot hear him.
The woman who cannot hear is not interested in making the situation easier for all involved. She wants to have all the consideration, leaving none for the other party. The woman thinks her disability allows her to insist the rest of the world, no matter the situation, comforms to her. I have been exposed to this sort of thinking before during my years of volunteering at The Lighthouse For The Blind.
There are a lot of fine people with disabilities, most in fact, who accept their lot in life and are considerate of the people who are not in their situation. They adjust and compromise, like all folks. They would never think that the entire world, everthing, must be rearranged in order to appease them.
Selfish and inconsiderate people come in all kinds of packages. Some of those people are blind; some are deaf, etc.
I probably have not made myself clear here. I have a lot of thoughts about these situations. None of them are meant to be malicious, demeaning, nor disrespectful. I find it very irritating when reason and logic are banished from reality in order to make ordinary folks the automatically guilty party in every situation where a "victim" of a disability is involved.
