“just because you are confined to a wheelchair shouldn’t mean you can’t enjoy a burger.”
So don’t go there, spend your money another place. I know disabled people who go searching for people to sue.
My wife was wheel chair bound for a while after her stroke and now walks with a cane. I have found that businesses will usually do whatever it takes to make sure her experience is as good as anyone’s. I think these kind of legal actions are just grabs for attention and/or $$$$.
