Whenever you board the SMB136C Citaro, you will feel that the
bus is brand new with a new lemon smell. Why? It's because the BC,
a malay SL wearing a specs, would always place the Glade Lemon
right beside the Coin Box when he is driving. And why is the bus
look so clean? That's because the BC would take his time cleaning
the bus and sweeping the floor after each trip.
Not a box but 2 box of air freshener 
. If it is not beside the coinbox usually at
the right end of the bus dashboard.
Anyway, few days ago I saw super shiny SBS2763U at bedok
int.
