People tend to check in during these times:
Buses normally come every 2 or so minutes, so no need to get into a crowded bus, just wait for the next.
Be prepared to guess the queue formations at the beginning. Keep in lane does not apply until it straightens out
You should definitely use either the left or the right queue...
Everyone should take the left q. Leave the right for me...
I don't think anybody really pays in the right-hand queue
Left hand queue on a morning is a good bet
