I lost my cards two years ago in Barcelona. I’m pretty sure it was user error, i failed to zip the picket they were on, and they may even have fallen out on their own, although certainly it’s possible they had help.
I was with my husband, so it wasn’t a serious problem that i lost all my credit cards, we just used his. (And i had left the joint card at home. It was only my cards that were lost.) I put the card holder into my wallet on the way to dinner, and noticed it was missing as we walked back to the hotel, when i wanted to stop and buy something. I spent an hour or two cancelling stuff. The ones with apps were easy. I had a little trouble with my HSA debit card, and the driver’s licence required me to know the number. (Fortunately, Google photos searched my photos and found one of my license.) I didn’t end up losing anything, except i had trouble renting a car two weeks later, before my replacement driver’s license showed up. Fortunately, Avis had the technology to look online to verify that my paper temporary license was legit, and rented me a car after Hertz refused to. (The employee looked at my paperwork that says I’m licensed to drive passenger vehicles and decided that was only a passenger license, not a drivers license!) I had to file a claim with the credit card company to get back my prepayment to Hertz. They lost a long-term customer that day.
The hardest item to replace was the card holder, as the type i like isn’t common.
(I do remove most of my cards when i travel. No need to take the “frequent customer” card from the place i buy cat food, nor my library cards.)
Anyway, it was certainly annoying, but ultimately not that big a deal. Just don’t lose your phone or your passport.
I think the video was staged.
