Last week with Mom and Pop in tow, I stopped to get gas in their car. I pretended to be a friendly small town gas attendant. I whistled while I cleaned the windows, checked the oil and air in their tires, jauntily tipped my pretend hat and cheerily said, "That will be $24.16, Ma'am." Mom handed me $24.25 and said, "Keep the change." I frowned, only .19 tip. Mom explained, "You didn't do such a good job on the windows!"
