A passenger at the next lane I was queuing up at, was directed by the security officer to go forth for her turn. As there was an immigration officer present, and the lane was empty so she went forth. When she reached the counter, the officer stood up and walked out from a her counter, and told her the lane was closed. Then, she moved over to another counter , walked all the way , and this other officer also got up, came out and rudely gestured that the lane was closing.
When passenger approached another officer, in anger, the officer quickly blamed the security officer even though it was their fault for their ignorance of informing that their lane was closing , whereas I noticed a few other officers who informed before hand.
