can't see anything wrong with that,would have done the same. i worked in Debenhams when i was younger & a downs bloke hit a middle aged man unprovoked. he reacted & hit him back,decking him & splitting his lip wide open. in stepped the downs blokes family going mental saying its wrong to hit disabled people etc but the man didn't know he was & just reacted. i didn't help matters by saying that i thought disabled people wanted to be treated like everyone else & therefore should except they are just as likely to get a smack in the mouth as anyone else in the same situation.
