caller: what time is your latest appointment?
me: it depends on the day. for an established patient, 5:30 if it's available. for a new patient, 5 pm if it's available.
caller: it's going to be for a new patient, and i need 5:30 pm.
me: (in my mind: what did i just say?????)
............ for a new patient, it's 5 pm because it's a longer session..........
