The single mother of two who ran a five-table restaurant had shopped, cooked, and served lunch and dinner all by herself for a number of years before he came in with his college books one day and could not take his eyes off he wear and tear of responsibilities on a woman not much older than he.  He offered to be her lunchtime server in exchange for a free meal.  It would ease her burden, and he’d savor a wonderfully complete meal for but two hours of labor each day.  In a few days, though, she said she’d prefer to split the tips with him than to have to cook him a meal.  Every day I worry about what different thing to serve you, she said.  It’s too much.  He thought to cancel the arrangement, but, instead, watched her go right back to work to do what needed to be done.  So, he went along and split the lunchtime tips with her.  Each day, he’d order from the menu and pay from his share of the tips.  The money left over made for a huge tip he’d leave her.  She’d return fifty percent of it on the next day, which he’d give back as part of that day’s tip, and then get its half back, which he’d give all to her only to get half of it back again.  When some two months later the children’s father reappeared, he paid her 8 for his last meal, and the tip he left was for 68.27.  He’d be gone; she’d have to keep the tip.  He had finally figured a way to give back to a giver in a way the giver could accept.
