If the customer gets to save $79995, they might be happy, but the sales staff and accountants won't be. Not only are openly rude names an issue and gender as you said. Misspelling a name, using a nickname for someone who prefers their proper given name, disallowing punctuation in punctuated names, or truncating a common name because your DBA didn't think about how many characters to use for a field are pretty disrespectful, too.

"Mrs. Jones-O'Reilley" doesn't want to be greeted as "Mr. Jones-O'Reilley", but neither does she want "Mrs. O'Reilley", "Mrs, Jones-OReilley", "Mrs. Jones-O'Riley", or "Mrs. Jones-O'Re". My first name is Christopher, and I can tell you how frustrating it can be to call somewhere that the clerk insists the account holder's name is "Christophe" because the DBA thought ten characters was plenty. Let's not even start on how often my last name's spelling is "corrected" as if I filled it out incorrectly myself and the customer service representative knows better. As frustrating as this kind of oversight is in customer service, I'm not sure what attacker would be quite so subtle as to only change those things.
