osaka airport transfer

The family offered a job to me, let me go to the Osaka Airport Transfer, but I am afraid that their language level not, if in case of foreign clients, I do not communicate with each other, so my family encouraged me to say is that language can learn slowly. But I really touch the Osaka Airport Transfer after work, I only know that I can speak English very well, because you can meet a lot of foreign tourists here, and English is the language of the world, so slowly, my English level has been greatly improved, and now I can with foreigners in English dialogue.
