Bus seat for lease?

Bus seat for lease?

From Tempo

As I went home by bus, a Bekasi-Jakarta air-conditioned limited express, I sat on the only vacant seat beside the driver and found myself cautioned for trespass before I could feel relieved about catching the bus.

The driver harshly told me to rise and stand because the seat had been leased on a monthly basis to a passenger, who would soon get on the bus at Rawamangun, East Jakarta.

The experience has made me wonder whether city bus seats can be chartered. That particular seat said to have been leased is usually used by a conductor. If seat-leasing is allowed, are passengers boarding after the lessee has left allowed to occupy them?
