Reasonable concessions can be made, at least out of sympathy for your fellow human. You can probably walk more than 1000 feet without serious pain. I can't, but you can't tell outwardly until I'm sitting on the ground in tears because of the pain. This line of reasoning is why finding a disabled parking spot when I need one is an act in frustration -- usually because people who don't need it park there because "it'll just be a minute, and there aren't that many handicapped people out there..." You can walk that extra distance. To me, that extra distance determines whether or not I can finish my day in a little pain, or have to stop early because it hurts too much.
