At around 10:30pm, I decided to go out and buy medicine for my niece because she was having a fever. While on my way out, the doorman/security guard stopped me and asked if I was a guest or if I will be checking out. I informed him that I was a guest of the hotel and I just want to buy medicine from a nearby store. Yet he did not believed in me (probably because I was wearing an ordinary clothes and slippers) and asked me to present myself to the receptionist. After the receptionist confirmed that I was a guest of their hotel, he let me out. After I came back buying the meds I needed, he apologized. Though he did that, I felt discriminated/insulted. I just hope that staffs must be taught to treat their guests equally regardless of how they are dressed.
