This reminds me of the crowd at 804 and 806 berth during evening
peak hrs.
FYI, 804 and 806 shares the same berth.
It is like a bus 804 comes. People queuing up at 804 will board the
bus. Normally, it will take around 4 - 6 mins depending on the
demand at that point in time and usually, the bus will be fully
packed. After this bus 804 has just left that berth, a bus 806
arrives and people queuing will board the bus.
Due to the sharing of the same berth by two very hot feeder
services like 804 and 806, a lot of time is wasted.
