Applied Leaves for Holiday

I have applied leave for my coming trip since two months ago. Mean reason for me to apply leave at early is because I am the only staff in the office now and I don’t want to make thing upside down once I am not around. I thought my boss would shocked after know I applied leaves for so many days, but he is not. He even requests me to buy him cigar bar in airport if find it is cheap..hmm…He really not worries about the office work at all!
