How do they know it isn't hers though, just because she appears fit and well?
My niece has a blue badge as she has quite bad scoliosis (curvature of the spine) This causes her great pain in walking and standing but you wouldn't know it by looking at her. She rarely uses the badge due to the amount of abuse she gets
Of course, if this woman is abusing the system, I'd like to see her get her come uppance but as it stands, no one knows why she has a badge
