Given a travel related situation, and given a specific question about the situation, summarize the question into a title

Ex Input:
On November 28th, 2014, in Moscow, the airport Domodedovo, I had my valid ticket to the U.S. going through Moscow-Frankfurt => Frankfurt-Toronto => Toronto-Minneapolis, MN. I hold a F-1  U.S. visa, and am a citizen of Tajikistan. When I came to the check-in counter, handed my passport to the representatives to print me my boarding pass and check my luggage in, they told me I needed a transit visa transiting through Canada, not going through Germany, therefore they did not check me in nor gave me my boarding pass. I checked Canadian embassy whether I needed a transit visa it says YES. below is the snapshot:

 

Then I tried calling the Canadian consulate in Moscow but there wasn't anyone assisting visa questions. I tried calling the ticketing agency I purchased the ticket from but they weren't any helpful in rebooking different tickets using the same airline before my departure time. At the end I was forced to buy new tickets to fly to the U.S. My questions or was my ticketing agency supposed totl inform me via email to get a transit visa? Was it a legit reason for the representative at a check-in counter in Moscow not allowing me to use my ticket? Would I have a good reason to claim a report for some kind of refund saying the agency didn't inform me I needed a transit visa? Or is it always up to the travelers to know they need it? 

Thanks! I'm just a full-time student and spending extra $650 is just too much for just not knowing about this Canadian transit visa. 


Ex Output:
I wasn't allowed to travel internationally because of Transit Visa. Is it a legit reason for not using my tickets?


Ex Input:
Specifically, I am taking the train from Taipei to Keelung, getting off at Badu and going to Pingxi, and then returning at night.

Do trains tend to sell out in Taiwan, or should I be OK purchasing my ticket immediately before departure?


Ex Output:
In Taiwan, must you reserve train tickets in advance, or can you buy tickets a few minutes before trains are supposed to depart?


Ex Input:
I know that it is more expensive / harder to find a car with an automatic transmission to rent, but why is that the case?

My first guess would be that autos are more expensive to buy, and that any excess wear and tear on the car caused by people who are bad at driving manuals simply doesn't come close to the increased purchase price.

Another option would be that people prefer to drive manuals, I guess?

This answer states that they used to have better fuel economy: What is the most common transmission type for rental cars in Japan? Is that still the reason for primarily offering manuals?

The above question & answers indicate that Japan is now mostly (exclusively?) automatics in the rental market. I believe the same is true of NZ and Australia. Are those countries ahead of the curve, or are European countries behind it?

EDIT: Of course, NZ and AU import a huge number of their cars from Japan, so that's probably trickled on through to the rental market (Japan produces less manual cars, countries can't import as many manuals, less available to buy, rental companies wind up with mostly automatics).


Ex Output:

Why is it harder / more expensive to rent cars with automatic transmission in Europe?
