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

Ex Input:
Besides the Turkish Lira, can I use US dollars and/or Euros in Istanbul?

I mean particularly for paying in taxis, groceries and vegetable markets.

If this is possible, is there any additional cost for this? I.e. will I pay more if I pay to a taxi driver in US dollars?


Ex Output:
What currencies can I use in Istanbul?


Ex Input:
In the last four days I've driven my motorbike from Milano to Kalamata going through a few nations on the east side of Adriatic sea, and in a couple of occasions I found myself crossing two customs to enter or exit a country (in both cases it was night, and cold, and I was freezing, and after driving for hours and hours, so I did not take note of which border...but probably entering Montenegro and exiting Albania)

Why is that? I noticed that in all occasions one custom asked for both my passport and my bike documents and the other custom asked for just my passport, but still it doesn't make much sense.


Ex Output:
Why two customs/immigration controls?


Ex Input:
(applies to all travel agents, I'm just using FC as an example)

Flight Centre - the world wide travel agent, often boasts "lowest prices guaranteed".  I've had trouble getting them to actually hold to this in the past, but generally if you can prove you can get the price elsewhere, like a print out of say, AirNZ's website with a price, they'll match or beat it.

Does anyone know if they'd be willing or able to match ITA's Matrix site?  It gives prices, but doesn't always indicate WHERE those prices are available.  If you took those prices and flight details along to a travel agent, like Flight Centre, are they able to find the flights for the same price, given all the flight details, assuming the flight is actually still available?
