You know what shits me?
My work email address is Firstname.Surname@PlaceofEmployment.com
When I send someone else in the organisation an email, it displays in their inbox as having come from Surname, First Name (Place of Employment)
My signature contains my name and department.
And when people reply to my emails APPROXIMATELY HALF OF THEM MISSPELL MY FUCKING NAME.
I'm not proud of this, but I give people two chances and then I start passively aggressively misspelling theirs back at them. "Dear Juliean", "Dear Caroll", "Dear Jaimey".
