Lol, that's fucking hilarious.
I asked a friend who was a server what they did if the math was incorrect. He said that they used the total amount.

It does say "I agree to pay the above total amount" so it is pretty clear.
I've done this my whole life. "Math" drawn cutesy if I have time. I can art, not math.
Make each digit of the tip a number that adds up to 9 with the subtotal except for the last digit. First is 7, last digit needs to add up to a value of 10

US tip culture is so weird. I’m talking about the comments as much as the pic

I'll never understand, how it can be, that I don't get a final receipt
Like, usually, I'm saying, I'm tipping (insert whatever), then in the US I'll hand over my card and need to trust them to put in the amount I intended to
I have no way of directly verifying
And everyone was angry at my just for asking and the poor barkeeper cried....as she didn't understand, that it wasn't about her...
Felt like an ass, just questioning the system
I have (intentionally) left a large tip when I'm hanging out somewhere for a long time with a low ticket value. The credit card company flags it and asks me via text to confirm that the tip is correct.
I don't know if it's strictly based on % or on deviations from your usual pattern.
Thankfully places in the US are slowly switching to those wireless POS terminals that are brought to the table. So many cards get skimmed when handed to servers and they leave your sight.
you keep the receipt, that way if you are charged wrongly you just sent the receipt to your CC and chargeback the restaurant.
it has happened to me a few times, maybe once every 2-3 years, the server will decide I didn't tip enough and my 10 dollar tip becomes 100 dollars. often they can get away with this because a lot of folks never check their receipts.
you are supposed to tip based on service level. it's entirely subjective.
0 tip for everyone. I order to go.
You haven't provided a service. Eating alone in restaurants freaks me out :v

That's the thing, it's just so much more effort
Doing some bar hopping at night and paying with card, it becomes completely impossible to really keep track, if the waiter just upped the tip
Or maybe I just was to drunk and have written poorly
It's just a shit system, without a way to directly verify on the spot

I'm good at math except after more than one drink. Ngl, I really like it when the bill has a list of percentages and totals to preview. I'd like it even more if we just charged what food and labor cost and got rid of this nonsense though.
Move the decimal one place left and double it for 20%. Do it for the sub total if you prefer not to tip on tax.
Been doing this for years. I evangelize it all the time, and people still don't understand, or they try to make it more complicated than it is. But it's literally THIS easy, so easy. It's not even math at this point, especially if you only double the dollar amount and ignore the change, a kindergartener could do it.
Yet people refuse to learn a "new weird way".
You don't have to understand it, just do it. This is literally the easiest way. I will die on this hill.
they can't do basic arthimetic. yeah it seems super easy to you, but most folks don't know how to multiple by 2 without a calculator. and they refuse to learn.
i've met people who work in mathetmatics, like stats, and still can't do basic tipping without a phone to do it for them. it's just something they refuse to learn or practice, mostly out of fear they will get it wrong.
