4. Not offering napkins - Now, there is a big difference between what a Westerner considers a 'napkin' versus what you usually get in China to wipe your mouth which is a 'tissue'. Paper seems to be a well protected commodity in China. I know that the schools that I've worked in treat a page of paper (especially in photocopiers) like it cost 5 yuan a sheet. It doesn't. It costs about 2-3 mao. When needing to make copies to give exams to students, I've had to pay to get copies made to give exams to my students. The administrators acted as if they were doing you a favor in making copies of exams so you can test the students.
