you are a kind man to try to help him even after the idiotic reply. (you are mjrj4 right?)
I am indeed (referring to me being mjrb4 there not bigging myself up about being kind!) Sometimes we get those sorts of comments in anger of the moment and then they apologise afterwards. Which is why at least to start with I try and just smile away and be friendly. I've never seen someone go on for quite that long with the insults though...!
Just makes me laugh really. And hopeful that someone showing that attitude will never get a job and I'll never have to work with or for them!
