Liaising besides interpreting

A long past client of mine turned up the second time with the patriarch founder of the company, an elegant, slow speaking, slow walking gentleman helping himself with an incredibly massive cane. After the speeches unannounced and unprepared, I heard about the Japanese side's preparation for the welcome diner I was not to be part of. They had chosen a Japanese restaurant, something classical and sumptuous as seen on the pamphlet I was shown.
I inquired about the seats, anticipating the excruciating effort the elderly man would have to deploy, with helpers, to get inside the hollowed cramped space under the table, what with the lack of back support. Japanese cuisine is exquisite. Japanese traditional sitting is not. They hadn't thought about it and took action to get special sitting arrangement, that is, chairs.

Is this part of the service a business liaison interpreter must deliver? Yes.
