Lately, both entering and leaving Thailand have been chaos. There have been endless lines. Note—this is also pre-Songkran.

Upon leaving 2 weeks ago. I noticed the e-passport line. No human intervention. You can just enter your passport and photo taken, and the gate opens. You exit Thailand. When I entered, I got the usual 30-day visa stamp. Now, I have exited with no departure stamp. Will this be an issue when I go back to Bangkok in 2 weeks?

BKK airport, reentry desk still inside immigration where is always was.

Automated exit gates somewhat operating with about 70% success rate. But sadly zero from two Australian e-passports today, sent off to a manual queue.
