Sadly for your friend, owning a condo doesn't cut any ice as far as getting a 30 day extension on a free stamp visa exempt entry π
As far as the wait time there in jomtien, it is what it is,
That's a busy office and if you wanna use them for an extension you wait it out.
Many times they have people apply for the extension and tell them come back tomorrow to pick up the passport..
Even IT Square Laksi Plaza has a couple HUNDRED people outside the door waiting to get in. It's just luck of the draw.. At least at Laksi, if you get a queue number you will get served that day π
