Jokes are best kept for once you reach the other side of the customs and immigration zone.
Sadly, two Dutch travelers were still having too much fun on their vacation when they arrived back home at Amsterdam airport, because they thought it would be a fun prank to switch passports and brighten up the day of the immigration official.
The joke was not appreciated, and the men were apprehended, held for several hours, and forced to pay a 250 Euro fine.
All for a stupid little joke.
So, let that be a reminder, don’t mess with people who don’t appreciate a bit of fun, as it will cost you almost $350!
