Second, lines arent the norm in all locations so I wouldn't find a sign telling them to queue up offensive.
In France, it is a national pasttime to cut the queue so maybe they know there is queue, I know I can't get over how many queues there are in the UK.
Which country you are from and which country you are talking about.
Your statement:
In Asia, people spit all the time on the street. They believe this keeps them healthy is just totally wrong
People spit everywhere , every country and they do because of their habit. I am yet to meet anyone (may be you) who spit because he / she thinks it is a good for them.
By any chance are you one of them who make these proposal?
I agree there is no harm emphasising on goodness. People know that they shouldn't smoke in public places and they should not get offended if there is a sign suggesting that.
However there are more important things in britishness specially the duties. your rights and responsibilities etc.
