I even pointed out to the cameras at the airport to make the point that her behavior was being captured by those. Even though I drank my water, deposited the bottle in the appropriate can, and spoke in a nice polite way to her, the security woman rudely yelled at me, hid her identity badge for me to not be able to capture her identity and one more time, another person in the security threatened me with not letting me board the plane when I took my I-phoneto take a photo of the first woman yelling at me (given that she hid her badge from me). On my way back I had another terribly bad experience because I was finishing a bottle of water right before entering the custom check point at the gate. Beware of the duty-free policies and be ready to be taken your purchases away from you. They also accused me of having an over-sized carry-on suitcase even though it fitted perfectly fine in the measurement box they have at the gate, and again threatened me with not letting me board the plane. Even though other passengers offered to take my duty free for me, the personal on the ground (whether that's the Airlines personnel or Tocumen airport personnel) denied the offers by others to bring my duty free purchase. The airline staff confiscated my duty free alleging its another personal item and threatened me with not letting me board the plane. ✅ Trip Verified | People at the gates (in both ways from the U.S and to the U.S) very disrespectful, rude, and intimidating.
