When visiting the cinema in Thailand please stand to show respect for Thai King Bhumibol Adulyadej and the Thai national anthem by standing when asked to do so.
If you do not stand for this tribute you may be seen as disrespecting the Thai King which is a big no-no in Thailand and may have serious repercussions for you.
Any criticism of the Thai Royal Family or the King of Thailand, King Bhumibol Adulyadej can see you jailed for anywhere between 3 years and 15 years.
There has been several well documented incidents of recent years where foreigners have been jailed for disrespecting Royal Thai King and the Royal Thai Family members..
Long Live the King.
