Dear sir
I am writing to apply for the position of waitress which was advertised in Friday edition of Gazeta Wyborcza.
To begin with, I am 18 years old and I am experienced, because for the last two years I have been working as a waitress in restaurant in England. I am sociable, kind, hard working and I have good communication skills.
Full details of my qualifications and work experience are included in my CV.
I wonder if you could give me some information about what you expect me to do as a waitress. I also would be very grateful if you could inform me about the salary and working hours.
I would be free to attend an interview at any time.
I am looking forward to hearing from you soon.
Yours faithfully
XYZ.
