It's a wonderful world we live in where because of the P.C. brigade people that can legally smoke a persecuted to the point that their lives are now at risk because they are not allowed to smoke in their work grounds.
I wonder how many more vulnerable people are going to be forced into dangerous situations just to keep the nanny brigade happy. I suppose if you are really callous you could say it serves them right, they don't have to smoke, but surely for personal safety's sake employers can let people like that poor nurse smoke in the car Park?
