I've had several customer complaints at work and I think it is largely because of how I come across as an American. I don't over thank and over apologize.
Are you from New York, or Georgia?
New York: Yo, jerk-face, are yuse gonna put it in the mail, or not?
Georgia: My goodness Miss Edna, if your hip is feeling better, it sure would smooth out the descrepency if you could pop that in the mailbox, sugar. Bless your heart. How're Jim and the kids?
