this reminds me of the time i was getting some food from Safeway last week. 
the cashier was adding on a piece of paper (not related to my purchase, i have no idea why she was adding). she wrote 90 + 30 = 100. realized her mistake, crossed out the middle "0" to make the answer 110. completely satisfied with herself. i didnt say a word.
