Ahhhhh There's a coolair bus, from outside I saw , with 36 guides..
I wanted to boarded it, but flagged the bus too late. Not my luck
to get 36 guides .
I suspect what you saw is actually a bus with svc 5
guides or other service guides inside.. Last time at PTB2 I
saw a bus with 'guides' inside too, so I boarded the bus and was
frustrated to see these were not svc 36 guides (forgot what I got
eventually).
