The story of how it became forever etched into my consciousness that «feliz navidad» is Spanish for merry xmas:
I was transferring at Schiphol in mid-December when I was 18. Obviously the entire place was all xmassed up. Me and my sister, whom I was traveling with, found a comfortable enough place to sit for a while that didn’t require us to buy anything — we were there for about 5 hrs, so that was very much a good thing.
In the middle of the floor in this massive hall in the airport was a giant artificial xmas tree. In the very top of the tree was sat some poor woman, who for as long as we could bear to sit there, was singing Feliz Navidad on repeat. Only that, no other songs or anything. Even though obviously Schiphol is not in any way in Spain or even a Spanish speaking country.
This was the same transfer btw when we learned that Schiphol had a very pink casino in which you could smoke. Simpler times.
I’m afraid or at least pretty certain that all the rest of my airport anecdotes that are even worth telling are frustrating or depressing ones, so that’s the best I’ve got.
