What evidence does the swamper give that the ranch boss is a "pretty nice fella"?

All of the above is indeed true, however there is one tiny
little detail that takes just a few words for Candy to utter. One day when the guys are
in the bunkhouse, he recalls one Christmas when the guys received a special gift from
the boss. It was a jug of whiskey. This must have been a tremendous gift to have
received in a day and age when money was hard to come by. Candy is an older man and
tells this little story reflectively and fondly as if it was one of his better memories
in a long time.
