May I ask, a cameo is for one whole day or one-trip only?
Or does it depend on the situation eg. lack of buses or bus
breakdown, emergency pullover etc.?
U must really know your fleet well to spot a cameo especially
the one that do x-overs so that u wont get confused btwn a cameo
and a perm x-over. If u really observe your bus fleet esp the
timing like e.g 500G reach BT merah at 6pm today while the next day
736T reach Bt Merah at 6pm. So its all about knowing your buses
well :)
