I don't have a problem with smokers, generally. I tend to not care at all.
...however, having spent nearly 2 weeks in New York, visiting my brother who was then at Memorial for treatment for nearly 2 months, that main entrance is ridiculous. The smoke cloud really is inescapable, and this being the premiere cancer institute in the world isn't so much ironic as it is unacceptable.
Then again, Memorial does do things a bit differently...
EDIT: Oh, I see that this is not Sloan...usually, when someone says "Memorial," they tend to mean MSK. :O
