Apologizing to somebody without ceasing as a way to coerce them, nicely, into what you want them to do.
Taken from The Yarn Harlot's blog yarnharlot.ca/blog - I pulled a Canadian Special... "I'm so sorry you think you have no seats. I feel terrible about this. Oh my goodness, I just feel so bad that you have to find one. I'm sorry I have to go to Toronto, I apologize for needing to really go tonight. Thanks so much for the help, I know you'll find me something, I apologize for being such a pain. No, no - I'm so sorry I can't go sit down. Please, accept my apology for this difficulty. I feel terrible that you have to do this for me."
