"If you've ever been to the city of New York during the past five years, you'll know that cab drivers don't always give off a warm and cuddly feeling. This was especially true for short trips, where I'd whip out my debit card and have to argue with the driver that I didn't have any cash on me 'til he finally gave in.\r\n\r\nLately, however, the attitude towards paying with cards seems to have shifted -- just in time for our new in-cab iPads. So, what's caused the change? Here's what one\u00A0Joshua Gross\u00A0found:\r\n&amp;quot;During payment, the user is presented with three default buttons for tipping: 20%, 25%, and 30%.\u00A0When cabs were cash only, the average tip was roughly 10%. After the introduction of this system, the tip percentage jumped to 22%. Those three buttons resulted in\u00A0$144,146,165 of additional tips. Per year. Those are some very valuable buttons.&amp;quot;\r\n\r\n\r\n&amp;amp;nbsp;"^^<http://www.w3.org/2001/XMLSchema#string>
