This is a subject close to my heart as this is something I too deal with. I have had my shoulder removed due to cancer, and I have a disability sticker. I only ever use disabled car parks when I am in pain or having a bad day and know I can't carry shopping bags or push the trolley. I have had many people staring and I even had one man get out of his car and come around the front of my car to check if I had a sticker.. I admit I completely lost my shiz at him. He backed off straight away apologizing. People need to realize that there are so many people out there with diabilties/illnesses that aren't visable and yes there are people who do use these spots who are not permitted to, but wish they weren't so quick to judge before knowing the facts.
