Which of these places did you last call or go to? What for? > I went to the post office yesterday to send a parcel to my aunt.

I went to the library to return some books yesterday (Я ходил в библиотеку, чтобы вернуть вчера некоторые книги).
At the weekend we had our car washed at the petrol station near our house (На выходных мы помыли нашу машину на заправочной станции возле нашего дома).
