Sometimes you get one with both intelligence and experience. Sometimes you get one and you wonder how they ever graduated the eight grade. It's the easiest thing in the world to book a one-way trip for your return and then get a refund for it when you're over there.
I always book my round trips from Europe because 1.) I live there, and 2.) they're cheaper. At the check-in counter in the States, they always give me a hard time when I fly back to Europe because my ticket ends there. Now, I always have my German residency card ready although they have no idea what it is. I could present them with my German driver's license and they wouldn't know the difference unless it's Lufthansa, which I never take.
Luckily my daughters are dual citizens. They use their German passports when entering and leaving Germany, and their US passports when entering and leaving the USA. That way, no one gives them any grief.
One time, an American woman working for my outfit was traveling on Continental Airlines from Brussels to New York. The stupid Belgian woman at the counter found her suspicious and called security to accompany her the whole way through the airport, even to the toilet, until she boarded the plane. I wrote Continental and told them they must have Al Qaeda sleepers working at their counter in Brussels, because the only reason they could have had to make such a fuss over my assistant would be because they were testing to see how easy it would be for them to smuggle a terrorist onto a Continental plane by causing an immense and uncalled-for distraction over someone who obviously posed no danger. They wrote back with the usual platitudes about how security was their highest priority blah blah blah. I wrote back again to explain that security, judging by the behavior of their staff in Brussels was absolutely the lowest priority, and that no one from my organization would ever fly Continental again due to the high risk to our personnel. I got some stupid form letter back which I never answered, but I'll bet their staff at Zavantem got an earful.
