I can walk... Won't get very bloody far at the moment though since I'm still recovering from an op but you wouldn't know anything was wrong unless I had my crutch with me (it's never very far away lately). I've come to have a fairly healthy respect for people who look fine but are actually in quite a lot of pain most of the time since this all kicked off last April... I'm lucky that I can fix mine. I think before this, I probably wanted to see 'proof' someone was disabled, s'not always that obvious though. You should report it if you feel that strongly about it.
