People have no idea that an overstay in Thailand can have consequences. They may have done 1,2,3 or whatever days and paid the fine at the airport and no other issues.
However what they don’t realise is that they got away with breaking the law (as most do). The unfortunate ones get caught at a police check point or similar and found on overstay and get incarcerated, sent to an immigration detention centre and deported at their expense.
Rarely happens but it does sometimes. This is why it’s horrible why so many people say it’s no issue to overstay. Because that shit hasn’t happened to them so assume it won’t happen to anyone.
On another side there’s plenty of stories from people that have had an overstay stamp in Thailand and subsequently denied a visa in a third party country because of it.
