Clean well lighted ending

In the end of Hemingway's "A Clean, Well Lighted Place", The young waiter asks the old man to leave early and denies him of another drink. This causes the old man to leave his peaceful clean well lighted cafe and causes the old waiter to talk to the young waiter about the value of the old man's time. While laying in bed not able to sleep because of his insomnia, the old waiter has an epiphany and realizes how important it is not only to him, but to the old man, to have a safe place to go to such as the clean, well lighted cafe rather than bars and bodegas.
