Today, I was at Costco. As I came out of the stall for disabled people, I was told by a woman who was at the sink area that "You don't have a disability! You shouldn't use that stall!" I just looked at her and said, "What an interesting assumption."
She asked what I meant by that. I said, "You made an assumption about my health and I said it was an interesting one."
Next she asked me why I needed to use the stall and I told her that if she wasn't my doctor, I wasn't discussing my health with her.
Before E-hell I would have explained every bit of my reasons!
