I want to apply to CVS in California for a retail store position, Do I have to apply online?

To start, she might have been legally blind, but still able to see up close or far away. She may have tools she uses to help her see what she cannot. What you should have done, and could still do, is ask her some questions about how she would accomplish the job. You might be surprised by her answers. If you really think she is a sweet girl, why not call her and interview her? You cannot ask her about her disability, but you can ask a question like --- a customer has found a shirt they like, but want it in a different size - what would you do? The customers asks what color shoes do you think I should wear with this - what do you say?

These stores usually have applications you can fill out.
