Pet peeves:
1. Countries that think they need a whole page-sized visa for their impressive graphic designs.
2. Immigration stampers who stamp on new pages when i'm running out.
3. The stupidity of requiring 6 months left on a passport for countries that only allow you in for 30 days or less anyway.
4. Countries without tourism take themselves too seriously: expensive visas, difficult to get, they hold your passport for ages... (eg, Recently went to Angola, and it took two attempts - had to cancel travel the first time because they wouldn't give my passport back, and approved it AFTER my trip was scheduled. The consulate is in singapore, and the staff don't answer the phone, and if you go there, they talk to you like you're a dog... Quote: "Sit." Wouldn't accept US dollars that had any crease in them, etc....)
