    You WRITE the tip amount on the receipt? How does the payment terminal know how much to take?

      It’s entered manually, usually at the end of the shift. It’s standard for most, if not all restaurants in the United States

      The server has to manually enter it.

      Here’s their bullshit workflow:

      • Print the check
      • Customer reviews it
      • Credit card is given to the server
      • Card is swiped/authorized at the POS
      • Server returns with the receipts
      • Customer then writes in the tip amount and signs on the merchant copy
      • Server takes the signed receipt and enters the tip amount back at the POS

      For whatever reason, the USA keeps using their signature, when the technology for pay at the table has been around for decades.

      Meanwhile, chip & PIN has been standard everywhere in Canada for the last decade, with some businesses using it for almost another decade prior to that. Mexico wasn’t far behind either, so it’s absolutely possible to adopt better methods.

      The transaction remains open until the end of the shift. At the end of the shift, the checks are closed out with the updated tip amount included in the final charge.

      Going back to the picture…thanks, now I have to confirm the restaurants math is correct and I’m bad at math.

        The quick way I was taught to eyeball it is to shift the decimal over one place to the left in the total, and double it. That’s 20%. In this case $30.53 > $3.053 > $6.106 ~ $6.10

          My coworkers would always tell me that when I worked in restaurants, but I never really figured it out with my A.D.D. brain and being distracted with serving customers. Now that I see it written out, that is helpful!

        I didn’t know a transaction could be updated after the fact. That’s wild.
