Spending $ to Save $

After purchasing an item at Kroger's, I noticed that I was $10 short of having the 10 cents off gas qualifier and yesterday was the last day of the month. So my son-in-law made a trip into the store for me to spend the $10. He bought pretzels and bottled water. As he rang it up, it was $9.99. So he threw in a Snickers bar to reach the goal and to enjoy it himself. Feeling so proud of himself as he gathered the groceries, he was tapped on the shoulder by a man behind him who asked to use his Kroger card. The man spent enough to cover the $10. J had a good laugh about that. He said next time he will just stand in line offering the card to all takers.
