    Great for calculating tips!

    Let’s see: the bill was $138.72, so I just need 138.72% of 20. And we can subtract 100% and just add the 20 back at the end, then convert the percentage to a decimal so (.3872 * 20) + 20 = 7.744 + 20 or $27.74.

    Easy!

      I prefer taking 10% and doubling it for a 20% tip.

      Take the total, moved the decimal one digit to the left, double it and round to the nearest dollar. I round up at the beginning and end as well which is either close enough or a dollar high if the change is small enough.

      $138.72 > 139 > 13.9 > 27.8 > $28

      Close enough!

        I either do this, or mentally divide by 5 (how many 5s make this number?), only caring about the closest whole number - I prefer to tip in whole dollar amounts to make the math easy.

        Eg. $39.53 is about $40, 40 is 8 fives, so tip $8

        If the service wasn’t great I round down instead of up.

          I multiply the tip by 5 to double check my math which is how I know it comes out as a dolllar higher sometimes.

          28x5=140

      I always just do 10% (easy because you move the decimal one place) and then either double that or add half of it to itself for a 15-20% tip.

        For sure. Reversing the percentages here makes this far more difficult. I just felt we needed to shittify this post a little.

        i just do 0. I feel like giving 20% more than agreed upon as default is crazy. I can not imagine employers giving 20% more wages just because i was doing my job? Why should i burn money?

          I tip because I’ve been reliant on tips before, and I know that expecting someone who is working for tips to single-handedly solve tipping culture is unreasonable. I don’t believe in solutions that punish the poorest person in the equation, especially for a luxury like dining out.

          You can already eat at places that pay a real wage to servers if you don’t want to tip.
