what was the effect on mr gessler of the author's remark about a certain pair of boots

The effect on Mr. Gessler of the author's remark about a certain pair of boots was that he was initially surprised and found the remark hard to believe. He looked at the author silently for some time, as if expecting him to withdraw or qualify the statement. Then Mr. Gessler asked the author to send the boots back so he could check them. He also assured that if he could do nothing to fix them, he would take the cost of the boots off the author's bill. Mr. Gessler seemed shocked by the complaint because he took great pride in the quality of his work and was confident that the boots should not have creaked.
