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

Q: In September 2012, I travelled by speedboat from Gasluokta/Kjpsvik to Vuodnabahta/Hellemobotn in Divtasvuona/Tysfjord, Norway. One of the timetabled stops along the way is Tjierrekluokta/Nordbukta. To my surprise, the boat at one point stopped seemingly in the middle of the fjord, in the pitch black darkness of a late September evening. After half a minute or so, a small boat came rowing from the void, took one passenger and his luggage, and rowed back. I asked other passengers, and they said that since there is no pier in Tjierrekluokta/Nordbukta, travellers have to do the last bit my themselves, rowing.

Well, this information was not at all reported in the timetable. Fortunately the place where we were starting our hike (Vuodnabahta/Hellemobotn) did have a pier and we could simply get there. Is there any resource from where I can tell whether I need to make special arrangements to reach a particular timetabled stop for a boat? Or does the company operating the boats take care of this if people cannot arrange it by themselves? Is the situation I describe rather unique, or does this more commonly occur in rural boat routes in Norway?

A: Pierless ferry stops in Norway, might one have to arrange own transportation for the final meters?

Q: When paying by card flight attendants usually ask to see your ID, to verify that the card in fact belongs to you. However it seems weird to me that pretty much no other merchants ever ask to see your ID, even when conducting purchases for thousands of euros (e.g. at IKEA).

So why do airlines insist on verifying your ID when paying by card? I understand that there's (usually) no Internet to verify the card balance on the plane (as suggested by TonyK), but how would one's ID help them out in case the card is empty?

Q: I will be arriving in Barcelona on the 13th of September and I will be staying together with my girlfriend for 6 nights.

Although I have a job, as students the budget is, let's say, a little limited. The hotel and the flight were already pretty expensive, so we would like to know if there are some places where we could eat a good lunch at an affordable price (10 euros, let's say).

First we will stay in El Guinardo neighborhood, and afterwards in La Vall D'Hebron. Nevertheless, the recommended places to eat can also be in nearby neighborhoods of the previously-mentioned ones or somewhere as "downtown" as possible.

If you think I can easily find affordable places to eat by just exploring the city, that also works for me.

I hope I don't sound cheap.
