I know it's weird. Yes, there were seats for the elderly and pregnant, but she was referring to a different set of seats (I forgot the color). Those seats aren't technically dedicated for locals but I think she meant that out of courtesy, foreigners should let the locals have those seats.
Yep, everything was crazy expensive! Except maybe for the train fares. My friend told me not to convert the prices to our local currency or I'd be frustrated every time. 😅
