Sure but I get the impression from this thread that such stories all happened a long time ago. Things have changed considerably especially since late last year. Drunk driving everywhere in Thailand can be fined up to 20k! When you go to the station you WILL end up in the system and if you get caught a second time you're in serious trouble with the justice department. So I say again, pay off all you can. That friendly police officer that used to slash your fine in half because you smiled and made a joke now received different instructions.
Again, in the past few months people I know have been paying up to 10k on the street. And even though that can be considered a ripoff it is still a lot smarter than going to the office with too much alcohol in your blood. Drunk driving has been made a serious offense, as serious as possessing drugs. The government is trying very hard to slash drunk driving accidents in this country.
