Yes will be due to sickness. Mine was about HK$60 short. It just goes to show precisely what your efforts are worth. HK$5.5 a day for going the extra mile, for taking that 100kg of fuel off or for bugging someone for a shortcut who has no interest in it at 3am. For coordinating a climb with another CX aircraft to save 1,000kg. Next time just think, its all for an extra HK$5.5 for that days extra effort. Obviously when you are sick you are putting in no effort what so ever so why should you be entitled to the extra cash, you could go somewhere close on a bus for that, or save up with two days worth of effort and treat yourself to a can of coke.
2 days sick! Thats a poor effort :-)
