Given a travel related situation, and given a specific question about the situation, summarize the question into a title
One example: The green carriage is of course first class. This would be our first preference with our 5 month old baby in lap, because of the presumably larger toilets for changing and whatnot.  However, the baby being a Western white baby... will occasionally babble, screech or cry uncontrollably for a little while.

Speaking in terms of Japanese culture, should we avoid Green class tickets if we are taking aboard a potentially disruptive baby?

Solution is here: Japanese train etiquette: Is it acceptable to take a baby in the Shinkansen Green Car?
Explanation: A person gives a detailed description about a situation where they would prefer to travel on the Shinkansen Green Car but is doubtful if doing that would be against the Japanese train etiquette since they will be traveling with a baby. The question is summarized as Japanese train etiquette: Is it acceptable to take a baby in the Shinkansen Green Car? for easy indexing the next time someone searches for a similar phrase

Now, solve this: I have to ask this because I'm Asian and we don't do any of these things there. I have been living in the UK and Germany for a while and I still can't understand how to do all of that in Europe.

If I don't know what to do, what's the best thing to do to stay safe and not insult people? I was in an awkward situation when I shake her hands instead of hugging. 

Solution:
When to hug, kiss, shake hands, or even "fist bump" in Europe?
