Just checked it out, you are correct! It's in chapter 31 of The Final Empire.
Another instance (perhaps not as good an example), in The Well of Ascension (chapter 52):
"She threw a Soothing on the couple, suppressing their concern and suspicion. Then, she Rioted their willingness to help. She wasn't as good as Breeze, but she wasn't unpracticed, either. The couple immediately relaxed."
