a McDonalds near my home used to have much more accessible drive through but they changed it.
One late dark night, I drove through and yelled at them that they made a mistake by removing that - they used to have someone you could order face to face but changed it.
They thought I was crazy. Nonetheless, it is still inacessible 
Screw these drive thrus....it is not only us deaf folks but also others who are speech impaired or not fluent in English verbally.
I never went back to that Mc Donalds again.:rl:
