Mr. Gray often travels to rural areas to sell machines to farmers. One of his problems has always been finding the proper hotel for himself, and often, when he reached a small village, he would be given a cold room with no hot water of good food after a long and tiring day. Late one evening, Mr. Gray arrived at a small railroad station. The journey by train that day had not been interesting at all, and Mr. Gray was cold, tired, and hungry. He was looking forward to a satisfying meal in a warm room, and then a hot bath and a comfortable bed. While he was leaving the exit of the station, he asked a local man, "Excuse me, I'm a stranger here in this town. Can you help me find a hotel to put me up for a night?" The man looked at him up and down and then replied, "There are altogether two hotels in our town." "Which one would you advise me to go to?" Mr. Gray asked hurriedly before he could finish. The local man scratched his head for a few moments and then answered, "Well, it's like this: whichever one you go to, you will be sorry that you didn't go to the other." 1.
