I am writing to apply for the 'job' (nie, lepiej uzyc wiecej formalne slowo 'post') of (brak przedimka) waiter in your restaurant.
I read your 'job' (niepotr- bo wiedza o co chodzi) advertisement in a newspaper (noi i teraz nikt nie wie jaki newspaper i kiedy byl wydany? takie detale trzeba napisac).
Last summer 'i' (dlaczego piszesz 'I' mala litera, jak wiesz dobrze ze to musi byc duza?) worked as (brak przedimka) waiter in cafe (ale jak dlugi i gdzie?). My employer was pleased 'for' (zle slowo, tutaj polski odpowiednik 'z') my 'job' (zle slowo, tutaj WORK). I also worked as a cashier in a supermarket (ale jak dlugo i gdzie?) , so I have experience in this profession.
I have good 'conact' (ortog) with people. My English is 'a very well' (nie, mylisz pojecia i caly czas myslisz po polsku - mysl po ang). I have no problems speaking 'Eanglish' (ortog).
(trzeba tez napisac ze wysylasz CV)
