I was reading this complaint about Tiger airways' policy of closing their check-in counters 45 mins prior to departure...

Is this the norm? What if you reach the queue with 90 mins to spare and it takes 46 mins to reach the counter as the queue is moving at a snail's pace? It seems quite ridiculous.

I can understand closing off the queue itself but not refusing to check in passengers already queued up from a long time before the 45 minute window...
