No restaurant including McDonalds, where the English language is not a requirement, or any other has a large print menu nor do they care. How about talking books through the Library of Congress, administered by your local library system. The form has print so small if you are over 40 you won't be able to read it. The cashiers at most grocery stores -Giant and Safeway in my area, Porters at Washington Nation Airport, Minneapolis, Sioux Falls, and every other airport in the country. They could give major airline personnel lessons in etiquette.
Regional airlines bend over backwards to help.
In DC at National airport, this wonderful young man ,Marvin, wooing the counter at the Greenleaf Deli in the Continental wing patiently read the menu, pointed out the restrooms and pay phones. Jeff a Continental flight attendant from Mpls to Newark went out of his way to assist me on the plane and to my next gate. Most people are very well meaning but don't know what to do. With my temporary low vision, I have no white cane or Braille training. I would like to pass a law that every architect, engineer, politician, government employee or person hired to even sweep the floors spend a week each year wearing night shades, ear plugs or in a wheel chair.
