Beggars are not choosers but if a man is very finicky about choices, he can be seen begging for options to choose from!
A chooser likes to make decision after carefully considering lots of alternatives. He therefore sometimes indulges in generating them, forcefully. He always wants variety in thought and action. So he pursuades fellow men and women to help him with pleasing alternatives. To his ignorance he actually begs to get a hang of variety in daily life!
A good example can be found in people who like to get their work done by being friendly to others. They portray astuteness in relationships but are in true sense doing the same job as done by those who seek help from others to earn their living. They live by begging.
