Disabilities & Bad Attitude

A news story is gaining attention about a security guard preventing someone with a disability from using a lawn chair while waiting in line at a concert. The person wronged got on Twitter, told of the experience, the company found out, the person got fired. (Link at the bottom.)

The issue of concern to touch upon here is with people without disabilities and ignorance. The security guard was a repeat offender of having a bad attitude towards the public so the person with a disability wasn't singled out because of the disability. Perhaps another person would have acted different.

The quote to take away from the security guard (regarding the lawn chair) "These handicapped people want everything. First they want chairs, then what? If you're so handicapped don't come this early, or better yet don't come at all."

In situations like these (not necessarily with the bad attitude) can the person without the disability be guilty of ignorance and the outcome not be as bad? Could the issue have been the same - not able to use the lawn chair - and not got the attention, if the security guard said, you can't use it because _________. If the security guard does it politely, is the situation as bad or is this just a case of disability ignorance?
