I do not find greed in my family, and I do respekt the way to talk and behave around this.
Doesn't mean I have to go temple and do everything they do for holidays rituals, I just being respectful around the family against my wife, as they are to me.
When it comes to Internal problems in Thailand, it's out of my reach, but for immigration I put on a poll or shirt, pants and shoes.
So far I have only experience once with my yellow book, and paid pocket money to have it all done in 2 hours. And that's the first and last time I ever paid any money to officials.
For the last yellow book and I'd card, no pocket money.
