Ive got a few handfuls of complex clients that get additional time,my front desk admin is really good about asking them if they ned more than 30 mins, and I review the appt book regularly looking for things that might be an issue, and we get them rescheduled for a larger time slot.

Oh you brought all 3 adult kids returns and your parent's stuff with you too, yea, you shoulda scheduled more time, they're in my drop off stack now!
