Yah lah! I was so surprised when I saw this bus back in service!
When it was the roving bus, they placed air-con compressors at the
back of the bus. The compressors faced the emergency exit. So when
the bus was parked for exhibition, the emergency exit would be open
to let air in/out to the air-con compressors!
The floor was also totally covered with all windows covered.
There was also a fake wall at the back of the bus. Behind the wall
was the A/C compressors.
But then now the bus looks normal!
