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

Input: Consider Input: When travelling between France and the UK via the Eurostar train, I have never actually been stopped by customs on either direction. I've seen some people being stopped, but it seems that it's on a somewhat random basis.

I'm considering traveling by coach this time, but I wonder if the customs are more strict, e.g. should I make sure to have receipts for all my electronic equipments (laptop, camera, etc.) and fresh fruit (to prove they were bought within the EU)?

Also, for coaches travelling during the night, is the procedure lenghty? The coach website displays the total travel duration, but not the amount of time one should be "awake" (e.g. waiting for customs or something else), so I wonder if I would be able to sleep during most of the time or if I'll spend, say, one hour waiting for customs clearance, or something like that.

Note: my question is more about the practical situation of a coach-based customs (which I have never actually been through) than the theoretical fact that one should always bring receipts for each valuable item in their luggage.


Output: Customs in coach travel between France and UK


Input: Consider Input: There are several services that many passengers are not aware of on-board airplanes simply because they are unadvertised.

For example:


Coat compartments. You can hang your suit in the airplanes cupboard! just ask a flight attendant!
Birthday / wedding cakes. You can ask the reservation agent for wedding or birthday cake and they will bring it to you on-board!
Stain remover. In case something spilled on your shirt, you can ask flight attendants to help and they will bring you the stain remover wet tissue and it really helps!


Are there any other common unadvertised services that exist on airplanes?


Output: Are there any common, secret services offered by airlines to passengers onboard?


Input: Consider Input: I have an F-1 international student visa which is still valid, and my passport is still valid, I just graduated and my I-20 expired 4 days ago. Can I still fly within the US? Will TSA agent ask about my I-20?

Also, I also have an expired driver's licence; I tried to renew, but the DMV gave me a temporary paper version. If I present the expired driver licence and the temporary one, would this be accepted?



Output: Can I travel within the US with expired I-20 and valid F-1 visa?
