I note that the re-entry permit booth at Don Muang is after immigration.

What is the proceedure then? Do you get stamped out and go get your re-entry permit.

Or do you ask to go past immigration, get the permit and then come back through to get stamped out?

Thanks in advance!

I believe you get stamped out and then go to the re-entry permit office.

Whether you get it before or after being stamped out would make no difference.

Many thanks.

If after stamping out, one wonders why you can't get a re-entry permit on arrival or even at an embassy overseas. TIT I guess...

I asked as I gave my passport. They called someone over and walked me to the "over stay" office. Where they issued it and stamped it in. I don't remember though if they stamped me first at the first booth where you look into the camera but I know there was some stamping going on at the overstay/extension office.
