Imagine you work at a nail salon, and a woman comes in with cerebral palsy hoping for a manicure. And you turn her away because of her disability. Pretty sucktastic, right? (Now, I know NOTHING about giving manis/pedis, but I know enough that unless someone is rude, inappropriate, or just a terrible person, you shouldn't refuse to serve them. ESPECIALLY because of a disability.)
Now imagine YOU are this woman with cerebral palsy. And you've been turned away by a salon because of a disability you were born with and can't control. But then an angel crosses your path -- an employee from Walmart. Who sets up a manicure station for you and gives you the mani you were just rejected from getting.
Long story short? In a world where you can really be anything...be yourself, but also be as good as this Walmart employee.
