In my college days I was a Resident Advisor (RA), essentially University representative in the halls to keep the kids from drinking themselves to death and/or dying in a fire.

We had a guy in a wheel chair on the first floor who wanted to be a RA. We denied it to him because the RA's would have to pull his ass out in a fire over the students that were able to walk and there was no way he could physically do the job.
