The service in Europe is great in many many places. My experience with US service is that it feels very fake most of the time. Plus, staff having their own table/zone means you cannot ask any other waiter to help out cause "it's not their table". That's one of the many problems with this tip culture.
I agree with the tiered pricing argument, but ehm, you know you are allowed to tip in Europe also right? If you are rich and feel benevolent, feel free to leave cash on the table. You don't need others to be forced into dark-pattern PIN machines or feel guilty for not paying more than the bill for that reason.
Strongly disagree regarding 1Password, their client is continually improving and it is IMHO by far the best password managing service now, I have tried most of the other ones before it. Really have no issues with their Electron switch, I didn't even notice it, still fast!
