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

Ex Input:
A friend of mine went recently to the USA, and he was saying that he didn't go through customs when leaving. After asking at the information balcony in the airport he was told not to worry. Everything would be handled at the departure gate. Only the ticket was checked though.

Is this normal? how do they register the exit?

Ex Output:

Ex Input:
I have dual citizenship. South African and Dutch.

I am traveling from Amsterdam via Heathrow to Nairobi Kenya.

I have exited Netherlands on my Dutch passport, but was warned not to show my South African passport at Heathrow.

I do not need a visa if I enter Kenya on my South African passport.

Should I be worried about this warning? And what should I do when asked for my visa at Heathrow(I don't have one)?

Ex Input:
I am from the US, and will be traveling to Basel, Switzerland for about a week. While there, I need to get from the airport to the hotel, the hotel to a certain location every day and back, and then back to the airport.

As I am unfamiliar with the road system and driving regulations in Basel, would driving there be unsafe? Is using public transportation a better recommendation?

Ex Output:
