While some of you might pretend not to notice the occasional elderly person giving you puppy eyes in order to snag your sweet disability seat on Muni or BART, few of us would go so far as to ignore someone on crutches. Here are a few who do.The creator of peoplewhositinthedisabilityseatswhenimstandingonmycrutches.com, explains his site like this: "I don't take pictures of anyone if there's an open seat within sight -- except for a few of those listed under the "Hall of Shame" tag. I also don't take pictures of elderly people, visibly pregnant women, or anyone who looks like they might have a disability. Of course, it's important to keep in mind that there's no way of knowing whether someone has a disability just by looking at them." Be sure to check it out. (Thanks Matty!)
