Huge tip

Bob Erb and his wife were traveling to bury his father's ashes when they happened upon a cafe named the Old West Express Diner.  They had lunch and met the owner.  After striking up a conversation, they learned that the owner's daughter had just been diagnosed with cancer.  On the return trip, they stopped at the diner again...this time to leave a tip...for $10,000.  Bob Erb had won $25 million in the lottery and has given money to others before.  $10,000 tip
