Walking home, I remembered being in a decent mood before I entered the store and now I felt pissed off. I’m in that damn Walgreens at least three times a week spending plenty of money. Why the hell would a cashier try to squeeze a little bit more out of me? And what business is it of hers if I want to drink Diet Coke? If I wanted to drink a gallon of Tide detergent, that’s my business and not hers.
