Asked to move seat by the busdriver for a weird reason...

When I was going on to the bus I showed my ticket and I sat down two rows behind the driver. The driver turned around and said: - Next time, please be seated on the other side so I have something nice to look at. Eh, hm Really!? Is that safe? If the busdriver watches you through the rear mirror while driving. Nah....he was just flirting...
