Could you refuse to offer a service to someone with a legal disability?

Yes, you can refuse to offer a service to someone with a legal disability if the refusal is based on legitimate reasons, such as the individual posing a direct threat to the safety of others or if the service cannot be provided without fundamentally altering its nature. However, businesses must ensure that any refusal complies with applicable laws, such as the Americans with Disabilities Act (ADA) in the U.S., which prohibits discrimination against individuals with disabilities. It's essential to consider reasonable accommodations that could allow the service to be provided safely.
