I thought I would vent my duty free frustration today.
I have recently returned from a great holiday in Taiwan.
On the way through the airports I wanted to buy some duty free gin.
At Taipei I was told that as the plane stopped and Bangkok I had to buy my liquor there. I suppose I should have challenged this but the explanation seemed reasonable.
However, at Bangkok they told me I should have bought it at Taipei and they showed me a card stating that when transiting though Bangkok form certain countries they could not supply alcohol.
I was very frustrated and never got my duty free gin!
I have emailed the Everrich duty free customer after sales service and will be interested in their reply. https://www.everrich-group.com/EN/Service/ContactUs. There was clearly no discussion to be had with the staff in Bangkok and it was very clear from the paper they showed me that they were correct and the staff in Taipei were not.
Next time I will know!
