You really expect them to admit being d'bags?Because in the past week I've dealt with people that have had a water heater to break. A timing belt to break. A unexpected bill to show up. A speeding ticket. And one that simply thought it'd be better to spend $150 more for something they couldn't wait two days to get.
Or they could not have bad luck and simply thought spinning a yarn would have been better than just saying "I changed my mind". Hint, being honest sits better IMO.
