Hi, I have a severe allergy to cigarette smoke. I also have major hip & knee problems & as such, I am unable to walk very fast. One of my major problems is when I try to enter shopping centres & I have to hold my breath because of people smoking just outside the entrances. Sometimes I trip during the "rushing" period & have twisted my hip & knee. Would I have any "comeback" to the owners of these centres or the local council for negligence and not providing a "safe entrance" for me to enter the shopping centres? I do not smoke myself & have nothing against people who do smoke - that is their decision. It's just the location that they choose to smoke that affects me. Thanks in advance.
