Upon entering a grocery store one recent night, I thought, "Good choice of the store to play Stephen Bishop's 'Save It For A Rainy Day' as background music. It was a middling 1977 hit that a lot of people wouldn't know today, but it's tasteful and understated. Maybe I should buy more than planned to reward them, even if it's just an extra can of soup or one more microwavable meal."
I didn't buy more than I'd planned, but I'm sure the store strives to put customers in that frame of mind. If Bishop's song had been accompanied by the scent of fresh-basked cookies, buying one or more extra items probably would have been tougher for me to resist.
