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

Q: I'm 15 days into a 30-day trip all across Greece (Athens, northern mainland, islands). Everything has been great except the long wait each time we are ready to pay our bill when we're out to eat or for drinks. In America, cleared plates or a credit card/cash sitting on the table is an indication that we are ready to leave. Here it seems they are in no rush at all. We've even waited 20 minutes (they weren't busy). They print the tickets and bring them out immediately but take much longer to take payment. Multiple times we've had to walk to them - which feels a bit rude.

My question
How do I more clearly indicate that I am ready to pay and leave?
or
Am I just being an impatient American not attuned to the Mediterranean pace of life?


A: How do I convey that I'm ready to pay my tab in Greece?

Q: I'm doing a house swap with another family, and as part of the logistics, at a certain point I have to leave my car for them, and they will pick it up a few days later. This happens to be in Newark, NJ, but the problem is pretty general.

We can't meet in advance to exchange keys, and I don't have a third party who could hold the key. 

Can anyone suggest a way to accomplish this?


A: How can I leave a car for someone if we can't meet in person?

Q: I want to go to Costa Rica and I am considering going to Panama and Nicaragua as well. I wonder though, what will I be able to find in Panama and Nicaragua that I will not be able to find in Costa Rica? It get the impression that the landscape, the wildlife and things to do (surfing, ziplining, snorkling) are all very similar in these countries. 

I would really love to see the wildlife as well as surf a little bit. I am not too interested in the culture, it is mostly nature that I am interested in. Wildlife, scubadiving, all these things interest me. Are these things significantly different in all these countries or is it mostly a price difference that occurs? 

I find it preferable to have access to wifi, as I am a traveling developer. I don't mind staying in hostels but I prefer not to stay in party hostels. Would love to meet people but I prefer to rest as well. 


A:
Panama, Costa Rica, Nicaragua
