there's is no automatic tourist visa on arrival. There's is a visa exempt entry where you have NO visa but are allowed to enter for 30 days and can extend that for extra 30 days.
the 30 day visa exempt ( no visa) entry is not a visa. It's permission to stay 30 days without a visa and then go to immigration to apply for extra 30 days.
my opinion is based on being well informed. By the way what you call "your ( union) flag" is actually my flag too. And it seems you think your singular opinion is ok. 🙄
