The job of the people who give out the placards is to determine who needs them, not who deserves them.

Well they do a pretty shit job. I'm not sure how anyone could deny that it's incredibly common to see fat people taking advantage of disability in this country. Sorry for losing my proper tone with you, it's not you, it was someone else. But I can't deny it anymore. We see people scooting around in walmarts all the time who clearly shouldn't be. They just use them because they are fat and lazy. Getting a placard is as easy as going to the doctor and saying "it hurts to walk more than 100 feet" and baboom, placard. I think lots of people take advantage of the system, but I think obese people are the most recognized, and not without reason.
