Teeing off on the 12th hole at a golf resort, we stopped to buy cold drinks from the young woman driving the beverage cart. As my buddy reached for his wallet, he said to her, "You're in great shape. You must work out a lot."

Flattered, she gave him a big smile and gushed, "Oh, thank you so much!"

The next day a different young woman was driving the cart. "Watch this," I whispered. I walked up to her and said, "Wow, you must work out a lot."

"Yeah," she replied flatly. "You should try it."
