Well, 1/2 hour actually means 25 mins. We are not psychiatrists but we need a few mins to cover for side changes and getting to and from the docks, etc. When you pick a pro and a time slot with the one hour clinics, we actually treat those as inventoried items so they don’t get double booked and do our best to make that happen. With the 1/2 hour clinics we take this as your preference, and will do our best to get what you want, but it is not always possible. Under certain circumstances, a refund may be given ahead of time, but that will be at the discretion of the clinic coordinator.
