In looking over a cafe menu, a woman noticed that both a chicken salad sandwich and a chicken sandwich were listed. She decided to order the chicken salad sandwich, but absentmindedly wrote "chicken sandwich" on her order slip. When the waiter brought the chicken sandwich, she protested immediately, insisting the waiter had erred.
Most waiters would have picked up the order slip and shown the customer the mistake she had made. But instead he expressed regret at the error, picked up the sandwich, returned to the kitchen, and a moment later placed a chicken salad sandwich in front of the woman.
While eating her sandwich, the woman picked up her order slip and noticed the mistake she had made. When it was time to pay for the meal, she apologized to the waiter and offered to pay for both sandwiches. The waiter said, "No, Ma'am. That's perfectly all right. I'm just happy you've forgiven me for being right."
Reckless words pierce like a sword, but the tongue of the wise brings healing.
