What is the new queue alert system for 90-day reporting at Jomtien Immigration?

Just back from doing a 90 day report at Jomtien. They have introduced a queue alert system which is pretty cool if your there to do business on one of those busy days. You can get your number then, if its busy, scan your ticket,go outside for coffee and not lose your turn as you will get an alert 5 places before your number.

You won't need it though for 90 day reporting as 2 desks can rattle them off in the region of 2 people every 90 seconds between them.

Still no sign of any further Saturday service.
