At least here in Argentina, clean bathrooms was a huge selling point in the 1990' for Burger King and McDonald's.
For example you can go to study to one of them with a few friends, and be there for hours because they have clean bathrooms, and from time to time one of the employees may come to offer coffee refill and ask if you want to buy something to eat with the coffee. [The free coffee refill changes from time to time. I'm not sure it's working now.]
Not that this specific quirk is covered in the novel, but a reading of Neal Stephenson's Cryptonomicon would certainly help make one understand the kind of necessary paranoia that would lead to this kind of (important!) protective measure.
You may argue that current payment processors do a poor job at b) but they do an infinitely better job than crypto since it's a division by zero situation.
But those are limited to purchasing things where ownership is also meaningfully controlled by crypto.
(They do have Jeri Ellsworth and some OGs from Commodore signed up to be part of the team though, and seem to genuine love the brand and have nostalgia for the C64, so I have cautious optimism!)
Reminds me of the story where some company was making a new VGA card, and it was rumored a rival company had implemented a buffer of some sort in their card. When both cards came out the rival had either not actually implemented it or implemented a far simpler solution
Former Ion Storm employees later revealed that Dominion’s E3 1996 demo was pre-rendered, with actors pretending to play, not live gameplay.
In most cases, there is, which is part of why a huge percentage of scratchoff prizes are won by workers at the place that sells them. Most players will scratch and redeem their prizes right in front of you, so if you watch a certain number of scratches occur in a roll and you know the prize structure of the particular card, you can calculate how many non-winning scratches you need to see for the odds to be in your favor.
I looked into this a few years ago and considered starting one of those stands that sells scratchoffs to do just this, but decided a) it wasn't quite lucrative enough to be worth it, and b) I wasn't sure of the ethics of skewing the odds against your customers like this anyway.
I feel like every time I swap to the Mac ecosystem it's a litany of "Hunh, that weird tiny thing doesn't work" issues.
PS: USB-C DisplayPort MST (display daisy-chaining) support that's been missing for... a decade and counting?
That said, it's not like everything is perfect, just 100% better than my drive-by experiences trying to have a gaming PC (dead, again), and an Android phone for testing purposes.
