My name is Andrew Wang, and I am a student at the business school at Boston University. I’ve recently been able to stay in a hostel in San Francisco for a week. Like any other college student, I bought the cheapest plane tickets available, which inevitably involved several layovers and transfers. Sandwiched between 24 hours, my journey involved a whopping 8 different stays at 6 different airports. Needless to say, I got well acquainted with airport bathrooms.
