I expressed my displeasure of these tickets at a bar I work at to one of my coworkers. They then pointed out that in Toast POS you can just punch in the total bill and it generates the tip for you

Oh that's good to know, I used to do math and then realized I'm probably being an asshole and stopped.

MATH RETURNS BABY!

[-] Lighttrails@sh.itjust.works 19 points 3 weeks ago

Remember math? It’s back, in pog form!

[-] BallShapedMan@lemmy.world 7 points 3 weeks ago

Oh I remember pogs. My brother's we're huge into them. I was just a bit too old for that fad to hit me. I was a Garbage Pail kid!

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.

[-] BigDiction@lemmy.world 12 points 3 weeks ago

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.

FYI, most places will just use the total if there's anything wrong with your math (assuming it's at least what you owe) so this is perfectly valid.

[-] Brokkr@lemmy.world 6 points 3 weeks ago

The addition is the hard part though, calculating the tip amount is easy. Can you write in just the tip amount and let them figure it out at the POS?

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

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.

[-] kevincox@lemmy.ml 8 points 3 weeks ago

It does say "I agree to pay the above total amount" so it is pretty clear.

[-] naeap@sopuli.xyz 13 points 3 weeks ago

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

[-] RememberTheApollo_@lemmy.world 6 points 3 weeks ago

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.

[-] EndlessNightmare@reddthat.com 5 points 3 weeks ago

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.

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

42.17

07.83

[-] rockSlayer@lemmy.blahaj.zone 8 points 3 weeks ago* (last edited 3 weeks ago)

$7.83

My method:

  • 42.17 + 8.00 = 50.17
  • 8 - 1 = 7
  • 0.17 - 0.02 = 0.15
  • 0.85 + 0.15 = 1.00
  • 0.85 - 0.02 = 0.83
[-] SatansMaggotyCumFart@piefed.world 17 points 3 weeks ago

Three cents to $42.20

Eighty cents to $43.00

Seven dollars to $50

Seven eighty-three!

Idk why people don't just give whole number tips. It's so much easier to just add $5 to something

[-] titanicx@lemmy.zip 12 points 3 weeks ago

Because it's easier to have a flat 50 out then 47.15.

I've done this my whole life. "Math" drawn cutesy if I have time. I can art, not math.

[-] some_guy@lemmy.sdf.org 6 points 3 weeks ago

Well, the Roman numeral M is 1000, so this is a pretty good tip. Not sure about the rest, but hey I'll take.
