Yeah it’s definitely a topic that one can’t cast judgement unless you truly know the situation.Back when my mom was alive she was restricted to a wheelchair and we had the HC placard available to us. We just left it in the home and whoever took her out to a store or Dr would just grab it. Many times people asked me why I left it hanging in the house and then park in the back 40 of the parking lot. I just found it much easier to do it that way than to struggle to find a open HC spot and then only find one that was open that was just as far away from the store doors than where I parked.
The only time that I actually used on was when my brother in law had his knees and hip replaced and was using a walker. But even then if I could just grab him a shopping cart he would just lean on that to help himself keep his balance and walk.
But as I found out years ago you never know just what a persons handicap is that allows them to obtain that placard. Some may look perfectly healthy but have a underlying condition. You just never know.
My scenarios that I’ve experienced I know the individuals quite well and sadly they were simply abusing their access.
