Border control MUST know how many people are arriving in any specific
half hour slot - all they need to do is look at the BAA website which tells them when and what and the estimated ETA and use a pocket calculator
The problem is that Border Control is seen as a way of showing arrivals who is boss - we're getting as bad as the USA
I've been going through Singapore for 35 years and never had to wait more than 10 minutes - and that was ONCE - normally the queue is 4-5 people
And don't tell me Singapore is not secure
