I'm looking for a word which describes the resolution of patience.
Example 1: If someone is waiting (being patient) in a room for his/her name to be called and it finally happens.
This also might include the act of running out of patience
Example 2: If someone is waiting (being patient) in a room for his/her name to be called and the office closes before the patient is called and the patient is forced to leave.
What is that resolution or action called?
