Shitty bun?

 I can't decide whether the Vietnamese are a humorous crowd, or that they are very literal. This is what we call a 馒头, i.e. a bun with no filling. I was trying to take a photo of a whole pile of them steaming on an open flame but the Tante tore into one with her bare hands to show me, "oh look, no filling."

I was like "eh, good for you?" What was I supposed to say?

Then she gestured at my wallet.

I am not brave enough to eat something touched by someone's dirty hands. But her son? toy boy? appeared and looked somewhat threatening, and she looked very impatient, so I became the proud possessor of a dirty bun @ 5000VND.
