The owner of a tiny but famous Sacramento burger joint said a lawsuit about handicapped access could shut him down. The Squeeze Inn, known for huge mounds of melted cheese on its burgers, violates the Americans with Disabilities Act of 1990, the lawsuit alleges. Kimberly Block, who says she has severly limited use of her legs, argues she suffered "embarrassment and humiliation" and that her civil rights were violated because of inadequate access inside the Fruitridge Road restaurant.
