My point is that it is within the realm of normal annoyances from other people and there should be a reasonable expectation of both politeness from the smoker and tolerance from others. A strong perfume, a fart, body odor, spicy food, and many other gasses can be encountered at any point from a similar distance, but nobody suggests punishing people for those.
I find the desire to over legislate things due to personal preferences about how other people behave is a bigger and more annoying vice than smoking.
I never use a case for my phone, and have broken them only twice, which is a better success rate than most people I know. I wouldn’t buy a sports car and cover it up to drive it, so why would I cover my expensive phone to use it? I do get AppleCare though, so I’m not out a full 1k if disaster strikes.
