After going into a gross, nasty, very-chinese bathroom:

Mariel: Don't worry, I brought soap!!
Nelly: Thank god!
Eveny: You carry soap with you?!
Mariel: of course, because there’s no soap in Chinese bathrooms. Do you want some?
Eveny: (laughing) No, thank you (Nelly and I exchange grossed-out glances)

I'm not kidding, this is what eveny says: Why are you washing your hands with soap?
Mariel: Nelly and I rate bathrooms on an A, B, C scale in SE Asia. An “A bathroom” means that you'll only get Hepatitus A from using it. A “B” bathroom means that you'll get Hep A and B from using it. A “C bathroom” means that you'll get all three. This was definitely a “C bathroom.”
Eveny: hahahaahahaaa!!
Mariel: You know, in America, all bathrooms have soap and toilet paper
Eveny: WOW!!
Mariel: and EVERYONE washes their hands. In fact, if you work in a restaurant and you're seen not washing your hands in a bathroom before returning to work, you'll get fired.
Eveny: WHAT??? That's terrible! Why?
Mariel/Nelly: Because it’s DISGUSTING!
Eveny: What if you work in a restaurant and you eat and drink too much and you have to go to the bathroom 10 times. Do you have to wash your hands ten times?
Mariel/Nelly: ABSOLUTELY!
Eveny: WOW! So strange!
