Never ever Miss Darling.  Ms. Darling is acceptable, but I prefer Mrs.  Mr. Darling is also acceptable.  I am also not Mrs. Husband’s-last-name.  I am Mrs. Darling.

Do not call me “Miss” by itself, “Ma’am” or “Sir” is preferable in these situations, 

If you’re not going to do this properly, just call me by my first name.  It’s simpler.

Though of course Comrade Darling always works too.
