Vector mathematics as we use it and code it is based on the right hand rule.

Agreed. That would be totally valid.
The top one is wrong because it violates the right hand rule.
Amsterdam also has a metro system.
Yes, these kinds of transfer numbers are easily possible (even though other posters have said you don't actually have 1,000 getting on or off at one stop). As an example, consider the subway of Toronto, Canada on its busiest line, Line 1. A subway train is 138m (450 ft) long with 6 cars (though there is no internal barrier between cars) and a capacity of about 1,500 people. Each car has 4 door sets per side, and these door sets are about 1.5m (5 ft) wide. People can easily fit through them in pairs, so moving 4 or more people per door set when in a rush is very doable. With 24 door sets (only one side opens at a station), that's 96 people entering or exiting per second, so 10 or 11 seconds for 1,000 people. If you think 4 per second per door is too optimistic, then it's 1,000 people in 20 seconds.
I've used self-checkouts in Canada and in The Netherlands. The ones here in Canada are just like the miserable experience you describe. Especially the weight sensor and the machine complaining. In The Netherlands I never had that issue (even with a second person helping me). I'm convinced companies have just turned the anti-theft settings up to aggravating false-positive levels over here.
At least where I'm from (Canada), bread comes with a clip holding the bag shut, not a twist tie. "Re-using the clip" means the clip the came with the bag. You can see that it's a different shape in the picture. This would be the equivalent of re-using the twist tie, if that's how the bread is packaged where you live.
In the book there's an additional interesting scene with Rico and the recruiter: Rico runs in to the recruiter as he's leaving the office. The recruiter does actually have prosthetic legs, and he's walking out the door. Rico asks why he didn't have them on before. The recruiter explains that his job is actually to scare away recruits. He's supposed to show potential recruits his missing legs as a consequence of his service. That way those that aren't really serious about it, those who are doing it because it just seems like a cool idea, don't go through with signing up. He then explains that the government doesn't require him to be a living warning sign in his off-time, so he puts on his legs and goes about his life that way.
Balatro doesn't have anything like gambling. There's no betting. You don't even have an opponent. The chips are only points, and the goal is to get as high a score as you can. The rules vary wildly from poker in ways that could never work with multiple players, let alone with real cards. It just looks like poker at the start and that description helps give you an initial idea of how to play.
Sceptre is the name I see whenever there's a discussion about who still makes dumb TVs.
If people aren't driving cars down a road because stopping at so many stop signs is unpleasant, why do you expect cyclists to bike down that road, when they actually have to physical work (not just pushing a pedal) getting up to speed again? Stop signs suck for bikes more than for cars. If cars avoid a route because of stop signs, of course bikes will avoid it!
