After taking the pictures, the guard asked me if I have a pen, I try to look it out inside my bag but couldn't find a pen, then we saw he had a pen inside his pocket, at first I thought he want to borrow a pen, he lead us into the VIP room just because he is funny, later on we found out he is asking for a non-monetary bribe
