Understandably, she was extremely upset by the note.
In August last year the Rotorua Daily Post reported on the family of a young cancer survivor who said they had been the target of abuse, threats and judgmental stares when using disabled car parks in Rotorua - even though they had a mobility card to do so.
Last week David Matthews, chief executive of CCS Disability Action, says similar situations where members of the public had confronted mobility permit holders about their apparent lack of disability had been made known to the organisation.
He urges people to use discretion when approaching people about the use of mobility cards, because appearances can be deceiving.
It is good to see people watching out for disabled drivers. But any possible benefit is outweighed by the hurt caused by assumptions based on a person's appearance.
