You may have read it before. I've seen it several times making the rounds. And I laugh each time. One source says it's written by William Schreyer. Here it is:

It seems there was a pretzel stand out front of an office building in New York. One day a man came out of the building, planted down a quarter, and then went on his way without taking a pretzel. This happened every day for three weeks. Finally, the old lady running the stand spoke up: "Sir, excuse me. May I have a word with you?" The fellow said: "I know what you're going to say. You're going to ask me why I give you a quarter every day and don't take a pretzel." And the woman said, "Not at all. I just want to tell you the price is now 35 cents."

First thought? What an ingrate! Not only is the vendor not interested in the man, she's looking to make an extra 10 cents.

"In everything give thanks, for this is God's will for you in Christ Jesus" (1 Thessalonians 5:18).
