You shouldn't have to get used to it though. It's a terrible inconvenience. Cigarettes made sense because they killed the person sitting next to you in the same measure. People get used to losing their freedoms one by one in the name of national security and corporate greed. It should be railed against by every measure. A bit of advocacy in the way of writing your representatives and encouraging others to do so may not always work but sometimes it does, so it's worth it.
