Got "held up" while departing
I use the manned IO booths for departing, not the e-gates, as I have a weak 3rd world passport which doesn't have the NFC chip. Normally I'm just stamped out in like 30-seconds or so. But this time the lady took maybe 2 or 3 minutes just starring at her screen or my passport, before finally stamping my departure stamp and letting me go. Afterward, she seemed to call what I assumed to be her supervisor, who gave me a head-node for some reason but didn't say anything else. This has left me anxious about my return. I've been in and out MULTIPLE times with this DTV with absolutely ZERO issues (literately never been questioned). What could she have been doing? I've got tonnes of in and out DTV stamps. Was that her concern? Hope I'm just overthinking.
