In china , many restaurants have not established smoking and non-smoking areas.
Those that have , often find their patrons do not observe the rule and the waiters do nothing about it , allowing some thoughtless diners to create clouds of smoke around them and forcing the non-smokers nearby to suffer.
People have begun studying “wine culture” but there are hardly any who study “smoking culture”.
Could it be because “smoking culture” is obviously part of a “backward culture”?
