Family members of a deceased individual properly filed an action for money damages in federal court against a funeral home for negligent infliction of emotional distress based on the alleged mishandling of the remains of the deceased. The funeral home timely and properly served an answer to the complaint. Thirty days later, including eight weekend days, the family members served a demand for a jury trial on the funeral home. The demand was served on a holiday. On the following day, a non-holiday weekday, the family members filed the jury trial demand with the court. Was the family members' demand for a jury trial timely?
