"In addition to being an outstanding Talmid Chacham and world renowned posek, Rav Hershel Schachter is one of the most prolific Torah teachers of our time. He recently celebrated his 80th birthday but hasn’t slowed down a bit, bli ayin harah. During his recent visit to our community over Shavuos, he gave almost 25 shiurim (lectures).
With all the public speaking, he often drinks hot tea to sooth his throat. When offered sugar or Splenda, he always declines and says he takes his tea plain. Once, the Schachters were guests in someone’s home and when offered tea, Rav Schachter graciously accepted but asked for it plain. The host, curious as to Rav Schachter’s preference for no sugar, asked why he wanted it so bland. After being asked several times, Rav Schachter finally relented and explained.
On a trip to Israel with the Rebbetzin when they were first married, he was at a meeting at someone’s home in a Kibbutz. The person offered Rav Schachter hot tea but he was concerned that the person may not be aware that ma’aser must be taken from sugar, so he happily accepted the tea but when offered sugar, responded, “I don’t take sugar in my tea.”
“So,” explained Rav Schachter, “to be true to what I said that day, for the last fifty years, I have never taken sugar in my tea, even if in truth, I would prefer it sweetened.”
Many people are casual with what comes out of their mouth. Consequently, promises are frequently made with no real intention of keeping them. “Let’s do lunch.” “I’ll give you a call.” “I will follow up with you soon.” “I will meet you there in five minutes.” “I’m on my way now.” These seem like inconsequential comments, hardly meaningful promises. And yet, if we say things we don’t mean, that aren’t fully accurate or true, or that we don’t plan on following up on, what does it say about the value of our words in general?"

Reminded me of the story of Rav Yaakov Kaminetzky who was invited as a bochur to someone's house for the seder whose kashrus he suspected wasn't up to par. So he said that he can't eat there b/c he doesn't eat gebrochts. From that time on he never again ate gebrochts on Pesach.
