The ADA would have to completely redo their standards as initially doors and ramps and toilet stalls were designed with standard sized wheelchairs in mind, not fat fucking whales. They have larger and larger wheelchairs and scooters and asses where NORMAL items break under stress. Can you imaging your restaurant choice being limited by which place had sufficiently strong chairs? Shit, restaurants would all have to get new toilets, get rid of booths and get chair rated to at least 500 lbs if fat became a disability.
