Translation of zealot in German

Do you know any people in Australia. I have delivered all the necessary information to the friends. Please give them a few more days to correct the letters (I was not in the office last week).
Before you make a reservation we need to check whether it has car parking, please wait. I will be in Switzerland next week. I am trying to get 4 or 5 days off. I will be back on the end of the year.
Some of the people had invited me for dinner and I joined them. I soon found out that they were eating at their apartment and were cooking by themselves. I found myself peeling raw potatoes.
