How many times do you show up at the aircraft outport and see ****ty forecast for HK, decide to take extra fuel only to arrive in CALM CAVOK WX??? And how many times do you see ZGSZ or VMMC forecasting **** wx and absolutely nothing out of the ordinary for HKG, only to arrive with CLK closed due to +TSRA SIG WS??? I personally lost count already about a year into the job....
