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

Example Input: I just reserved a room at the Hotel Vier Jahreszeiten in Berchtesgaden, Germany. I went through the booking website and provided all of my info, but they never asked for payment information. I didn't initially receive a confirmation, so I emailed the hotel to ask if the booking had been successful or if I needed to try again. After that, I did receive an email confirmation with all of the correct information.

It seems odd that I could reserve this room without providing a credit card, especially since their cancellation policy says they will charge for one night after a certain date. Should I be worried about the validity of this reservation, or is this practice fairly normal in Germany?

Example Output: Booked hotel, but never asked for payment information

Example Input: I travelled alone in Japan for business, for 10 days. I declared that I bought items for $550,  well under the $800 limit. After my non-stop flight from Japan landed at YYZ, I was directed to secondary inspection at approx. 5 PM. The female CBSA (Canada Border Services Agency) officer inspected all my belongings and the receipts for my purchases. 

At 5:15, she started alleging that some other items (like clothing, 1 backup pair of eyeglasses, 1 pair of sunglasses) were bought in Japan, as they looked too new and clean to have been bought in Canada. Of course they did...I'm a business professional! But  they aren't that new in fact, and I bought them in Canada. 

I repeated that they were bought in Canada and were brought by me to Japan. She said that she didn't believe me. She  demanded proof that they were bought in Canada. I answered that I bought the clothing in Toronto and can't remember exactly where or when. I told her the name and approximate locations of some opticians that I remember. It feels unreasonable to expect weary travelers to remember details on the spot, without  records on hand.

She then got angry and rude. She said  that I was being evasive and warned me not to lie. She threatened to seize my items. She admonished that I, not she, had the onus of proving to her that I bought these items in Canada. 

At 5:45, I requested politely to speak to her supervisor. She asked why. I answered that I was a little jaded from being reasked the same questions and repeating the same answers for 30 minutes. She got  more offended and ruder, when she raised her voice to ask why I thought she was wasting my time and asking irrelevant questions. I answered that I never said this at all. She said that I don't need a supervisor, if I had nothing to hide. 

At 6, I reiterated my request for a supervisor, and she bitterly told me to be patient. At 6:20, a supervisor showed up, and we repeated the same questions before I was allowed to leave at 6:45. 

In all, I spent 105 minutes in secondary inspection. My tone was always deferential and polite. 


What can be done in the future, to avoid this kind of wrangle, and waste of time? What could I have done better? 

I don't intend to complain against her...I'm too frightened of retaliation and being black-listed.  
Has this wrangle has already put me on some list and blemished my CBSA records?


Example Output: How do I stop a CBSA officer from wasting my time, by falsely alleging that some of my items weren't bought in Canada?

Example Input: Is it possible to buy Indian Foreign Tourist Quota railway tickets at the Vasco Da Gama railway station? This post from 2012 says it is possible, however mentions restrictions on tickets at Madgaon, and was wondering if a similar restriction applied to tickets purchased at Vasco Da Gama... http://www.indiamike.com/india/indian-railways-f10/booking-offices-for-foreign-tourist-quota-in-goa-t166621/

Example Output:
