So, alternatives:
I guess it’s 2 or 3 for me depending on the mood. “I want to fight for whatever” is way more frequent than having cash on hand 
I took this over here from us-integrity-visa-coming-soon because it fits better.
I wonder what stores like Aldi or Lidl etc. do with the tip some people give at a self check-out? Hand it over to the staff? Why do I not believe that for a minute?
@TinyK Is the software obvious that by clicking Next you can skip the question?
Actually I think we should get a tip (=discount) for doing all the work ourselves. Guess everyone would click on 20% when asked how much they want. 
Even if it is not obvious at the beginning, you gain experience with it.
I’m only two weeks in Canada, and I already learned all possible interfaces of the payment terminals and can easily avoid tipping in take aways and self service restaurants. Yesterday the interface was in french for some reason - probably to make it harder for the tourists to understand and make them choose one of the default options (something like 18%, 20% or 25%).
maybe because you’re in Canada?
I’d be very surprised to see French used anywhere to the west, or north, of Toronto.
On my recent trip I was surprised with the frequency (ie just about always) of being asked to tip when using Apple Pay. Got caught the first time but after that regularly just hit ‘other’ and then “0”. Absolutely no-one complained or objected, or even seemed to notice.
The other thing I noticed was the inflation. While you may have been asked for 15%, 18% or 20% in the past it is now 18%, 20% or 25%. In one fancy resturant it was 22%, 25% or 30%! I just chose other and entered 15% as the service wasn’t that great. And am regretting I was that generous.
I don’t recall specifically, but give that the whole country has both French and English as official languages it’s possible that the banking systems do as well. And that they use something from the card/issuer to determine which language to use.
When I use my Swiss cards within Switzerland they always default to English, so I imagine it’s been set as a preference somewhere.
I don’t know who you have been hanging around with… But I have been here over 30 years, most of my friends are Swiss and I can’t remember a single instance of us getting up from a table with leaving a small tip of some kind.
Think the SW developer should also get a tip.
the surprised complaining is not about that but about self-chekouts and self service places.
Let’s face it, when I have to start tipping Migros for me shopping there …
It’s very different in the different venues. In the shop/small cafe at the hotel where we are staying it’s 5, 8 and 10. Sometimes it starts from 15, sometimes from 18. The interface on the terminal is very different. In Switzerland it seems to be more standard.
Exactly. Well, grocery and other stores don’t have tips option on the terminal, but most of the Starbucks and other similar fast food restaurants do. Imagine if we were asked for tips in any Migros Take Away or Migros Restaurant. Crazy…
BTW, we meet Swiss all the time. Even in some remote towns. They are everywhere.
Things to consider next time: splitting a bill in a table with several people is too much work.
Restaurateurs want the benefits of significant revenue coming from a single table, but none of the work or annoyances related to it.
But, there are ways to avoid annoying service staff with bills. Just be brave:
Can’t wait for Digitec, Brack, Coop, Migros … sending a monthly bill to the house (or even to the village), telling us to sort it out ourselves.
"A note on the menu stating that a request for separate payment should be made right at the start has also been discussed. “Then the team can record the bills at the till right from the start.”
That would be okay.
I just imagine Mr. Restaurateur in tears complaining about separate bills like rent, electricity, food supplies, water. Life is so unfair, if bills came together life would be easier, right?
Heck, one salary payment and employees should decide how much each one gets, bliss 
The waiters complain about a problem they create themselves out of pure convenience and laziness. They want to have the cake and eat it, too. And in their entitlement expect the customer to solve the issue they created themselves.
It’s easily solved by creating individual bills from the get-go but of course that’s too much hassle and too error-prone.
yeah, plus they could sneak in a few kWh electricity, a m2 rent etc. and it would not get noticed.
Absolutely. One payment a year, they can also sort out who still works there and who doesn’t.
These screens are so convenient. We have one in our local Döner restaurant now. So much easier to order. Even better if you can also order while you are in your way, like in Holy Cow.
In my opinion, the only reason it’s so time-consuming for staff here is that the computer systems aren’t set up to make it easy.
Splitting checks has been easy at most restaurants in the USA for at least two decades. It’s common for people to state up front who is sharing a ticket. When the server enters orders into the computer, it’s by table number and by seat number. The only splitting necessary between diners is if there’s a bottle of wine or something that is shared by all. In that case, one person often says to put the item on his or her bill, and the others usually chip in some cash. 
Friday office lunches in the '80s…every person got a separate bill. Happy days.
