Q: My friend had a booking with Alitalia from London to Tokyo involving (due to pricing) a Milan-London leg on the return that he's not going to use.

I know the taxes for the unused leg (GBP 22) can be refunded on request, but what about the "additional charges" (GBP 34.20)?

He has completed all legs that he was supposed to use.

Below is a screenshot of the price for the unused leg

Q: 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.

A:
What currencies can I use in Istanbul?
