"Smoking"

I am lead to believe, not partly by all the signs put up,at considerable expense, that, except for designated smoking shelters,the hospital ground are totally no smoking. I have spent one and a half hours at the new unit this morning and witnessed visitors and several patients, some wheeling drips, standing just outside the door near the central treatment suite smoking. One was even directed there by one of your volunteers! I find this not only unbelievable but also disgusting. Any one entering or leaving the hospital has to do so through a cloud of toxic foul smelling smoke, not to mention the butt ends on the floor outside and also Inside between the doors on the carpet. I asked a volunteer about the no smoking policy and they replied that nobody bothers?!? I also asked them where I could lodge a complaint. Unfortunately they didn't have a satisfactory response to this either. I would like a response to this at your earliest request. I do have photos which I am able to provide to you. If no response I will have no problem taking this complaint further.
