“A lack of blank pages in the passport”
This reminded me of that song that goes “ Hey Mr. Tally-man, Tally me bananas. One banana, Two banana” Etc. Etc.
I wonder how a passport would not have the amount of required pages.
Every time you enter a country, you go through passport control and they stamp your passport on the blank pages at the back. People tear out pages, if they don’t know how risky it is, in order to conceal their previous movements. If you get caught doing that, as she found out, you get stuck where you are. That airport person was on the ball.
