Re:You Want 20% for Handing Me a Muffin? The Awkward Etiquet... by mikestew on Wednesday October 17, 2018 @02:34PM (#18242151)
I feel that the tips should be calculated based on the exchange I had with the establishment/person

You're free to calculate the tip however you like. Just because some junior programmer took the easy way out to make the math easier doesn't mean you have to along with it. I don't recall a digitized tip screen that didn't let me enter a custom amount.

True, but it is dishonest at best and negligent at worst. The 'error' is in their favor, not the customers. It sends a bad signal that they are willing to 'cheat' you over less than a dollar. What else could they be 'cheating' the customer on?
