I see 2 possible answers, either one could be correct - feel free to pick the one you see as the most accurate:
1) The office is understaffed and has a large number of long term staff who have accumulated long vacation entitlements, they work as fast as they possibly can within the mandate for public safety, but there are times when a delay is unavoidable.
2) They're a bunch of anti-gun bureaucrats, who are not only riding the gravy train for all it's worth, they're doing it so damned slowly that if it gets any worse they'll actually be moving backwards. The only way some of these illigitimate offspring will see an application to transfer is if it gets glued to the water cooler.
