I met John when I was working at a library in Singapore. He had a routine he performed every morning when the library opened. First, he would greet everyone loudly and shake hands with the library staff present. Next, he would head to the counter to scan his expired identity card as he half-mumbled and half-declared to everyone that he has paid his bills to the government. Then, he would show the library staff his documents and again declare that he has paid his bills, before finally heading to the multimedia station.
