I use a cane, and, yes, I am denied exit row seating. I accept this. Anyone who is impared should not be the the exit row. Recently, on another airline, I was told I was "too old" for the exit row, then they saw my cane. I guess two strikes. I do not like people seeking special treatment when not needed. I would happily give up my cane and handicapped stickers, if I didn't need them.
