 As tickets are paid and printed at the offices (major stops) or by an employee along the road (smaller stops), there is no need for a conductor to collect the money in the bus.Tickets can be issued in advance, so they might be sold out quickly at busy times (specially Fridays, Sundays and at the beginning/end of school holidays).In contrast to the Share Taxi, this form of transport respects the schedule rather than waiting to be full.
