Sorry for the discourtesy you experienced (which, sadly, is pretty normal), but I'm glad you get to have a fresh start with someone new.
The best departure I ever experienced was when our dentist of long standing retired. He sent every patient a formal letter announcing his retirement, naming the new person taking over the practice, and inviting everyone to an open house so they could say goodbye and meet the new dentist. Now that was classy.
And when we got there, every square inch of counter space was covered with cookies, cake, candy . . . when we reached him in the reception line I asked, "drumming up business??"
