I was going past the station around sunset, so I stopped and stuck my head in. When the Constable on duty asked me how he could help me, I pointed out that it was sunset and it was time to lower the flag.
He asked me to repeat myself, which I did.
I think he was quite stunned to see that a member of the public would bother to walk into the station to tell them that.
He replied that he was aware of the protocol, and said that they couldn't always take it down - presumably due to resourcing problems and other more pressing matters blah blah blah. I don't mind it not being taken down from time to time, but I'm not going to stand for it not being taken down for months on end. I guess I will just have to front up at the station every day at sunset and repeat my mantra - the flag will be lowered at sunset. After a few visits, they should get the point.
