How do we stop our Japanese-speaking friend becoming the interpreter for the whole holiday?

Aya is choosing a pastry in Osaka when her friend hands over another phone. “Can you just ring this place? They haven't replied.”

It is the fourth call Aya has been asked to make that morning. She speaks Japanese; the three friends travelling with her do not. When they planned the trip, she offered to help with their first accommodation check-in. Now they pass her menus, booking problems and questions they have not tried asking themselves.

Aya likes talking with people and has sometimes taken over without being asked. She wants to stop being responsible for every answer. Her friends say they thought this was part of exploring together, and one worries that refusing help means they will keep making avoidable mistakes.

What would be a fair reset halfway through the trip? Aya wants to finish choosing her pastry without turning breakfast into a rota, but “just this one call” has already used most of the morning.
