Our Train arrived in Da Nang at 6am. We walked to the main road and got on the bus to Hoi An. The attendant was wearing sunglasses, and a mask covered her mouth. A local woman who boarded the bus in front of us paid 20,000 dong. I tried giving the attendant the same amount, but she demanded 40,000 each. After getting ripped off – and threatened with a knife – in Can Tho, I was already leery of Vietnamese bus attendants. And now we were being charged double, simply because we were foreigners.
