It's disgusting. About a year ago I spent all day complaining to various departments of a blue chip company after one of their contractors spat at me in the street.
I became so persistent when I realised it wasn't being taken seriously - one department asked me in all seriousness whether the man really had spat at me or had 'only' gobbed a greeny inches from my feet by 'accident' because he had a cold. He had done it deliberately btw - I guess he has a problem with women walking along minding their own business - but that's what tissues are for isn't it?
At the end of the day I was told this workman had been identified (not difficult because I'd emailed them his picture) and wouldn't work for the big company any more. No idea whether that was true but I was still made to believe that he was a poor lamb and I was being a bit precious and costing him his job because of a misunderstanding.
