When I was a university student a long time ago, I travelled to Paris and took a cab from the airport. I arrived at the hotel without any problem and paid about 50 CFP Franc.
A woman I met was charged 250 CFP Franc for the taxi fee from the airport to the hotel with short sightseeing without agreement. She paid what a taxi driver said. So she was afraid of taxis in Paris after that, so when I got a taxi with her, she cried all the way back to the airport from the hotel, saying she was scared.
In fact, it is common to happen among Japanese people.
Japanese people have a language barrier and are not good at speaking a foreign language, so they never complain and pay the crazy price without complaint.
