instruction:
Given a travel related situation, and given a specific question about the situation, summarize the question into a title
question:
Flights out of London Heathrow do not contain departure gate information until about 45 minutes before the flight is ready to depart (presumably so you spend more money at the duty-free). Are there any public APIs or resources that will tell me which gate my flight departs from before the Heathrow departure screens do?

answer:
Determine gate for departing Heathrow flight

question:
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?

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

question:
I recently went to Japan (specifically Osaka and a few other places around Kansai) for the first time in my life, and had an amazing time. One of the many cultural differences I noticed was that Japanese ATMs were rather different to those in other parts of Asia, North America, or in Europe.

In particular, every one I encountered presented money towards the user displayed "in full", usually up from the ground, as if it were a pile of cash resting on a table. Every other ATM I've ever used shoves out a (probably) thin wadge of notes, with the edge of the wadge presented towards the user, and the face of the notes hidden until the user removes them.

Why? Given the extra engineering effort in making machines like this, and the vast amount of cultural background to money in Japan, I'd be surprised if it's sheer chance.

Here's an attempt at illustrating what I'm on about:

Japanese ATM -- Yen come out of a grey slot, presented face-up towards the user, not held on any side:

[e.g.] US ATM -- Money comes out in a thin wadge held by rollers:

answer:
Why do Japanese ATMs dispense money stacked differently to those in the west?
