If asked for a random thing that just got on her nerves and made her want to yell. Ariel would have said that it was irresponsible tourists.
Those people who, when visiting another location, forgot that just because they did not live there. It did not mean that other people did not call that place home.

The people who were disrespectful, peeing in public places sometimes even going as far as to harass the locals.
