Tiring, very tiring

It has been a tiring day today. From morning till the end of my work shift, I had to attend to one customer. He, a foreigner who is also a doctor wanted me to help him prepare his documentations. He wants to apply for work in Malaysia. However, due to many other customers also requiring my attention, the work prolong for more than 6 hours. It is so tiring to work like that. And what is worse is that after everything is done, he asked to be given a discount. What lah.... the charges are already so cheap and yet still want to ask for discounts. Next time, I won't agree to help him unless he agrees to pay for the full amount.
