It's painful to watch an otherwise successful person whip out a calculator to make sure they don't accidentally give their server an extra 30 cents on an ~$18 l

  Tip calculators all go the wrong way (well, all the ones I've seen do). Suppose I order a pizza and it comes to 16.12. A typical tip calculator will tell me that with a 15% tip, this would be 18.54, and with a 20% tip it would be 19.34. I don't want to screw around with that .54 or .34. I want to give the delivery person an integral number of dollars. Probably hand him a $20, and tell him how many dollar bills to give me back. I made a tip calculator Dashboard widget to calculate tips from that perspective. With this widget, I enter 16.12, and it gives me a little table that looks like this: $17.... 5.5% $18....11.7% $19....18% $20....24.2% $21....30.5% I can glance at that, and see that $19 or $20 for combined $16.12 pizza plus tip are reasonable options. If it were summer, I'd probably go for $19, especially if I could do that without breaking a $20. If it were winter, I'd probably just go with a $20 bill and no change, to get the transaction over with as quickly as possible so I could close the door and stop losing my precious heat.
