Maybe they made sense in the 70's but most public places are already smoking free so people must be more conditioned not to light up, I hope?
Oh yes, those good old 70s / early 80s when you could even buy a (literally) smoking ticket! Now please don't call me Shirley
I was reading the other day that JR Shinkansens still had smoking section, but I don't think JAL / ANA flights still do?
