The woman who helped me at cashier was very rude. I asked to charge my credit card in NTD instead of USD. She didn't understand and acted like what the hell does that mean!? I speak Mandarin Chinese fluently. It ended up her colleague sat next to her answered my question.

However, the doctors, pharmacists, and nurses were professional; volunteers were helpful and very friendly.
