Funniest experience I had was when I was going through Narita, as a 20 something year old on my way back to the states and using the bathroom facilities at the airport, and old momoson coming in the restroom cleaning up, despite some 20 men in there watering their horses. Me amongst them. This momoson just mopping the floor, indifferent to whom was in there or not. (She probably had grand kids you know....) Back in the states, people would freak out.
