Dear Sir or Madam,
I saw your advertisement in a local newspaper. I would like to apply for a job of waiter in your restaurant.
I am 16 years old and I am studying at Prienai high school. I have been studying English for about eight years, and I speak it quite fluently. After finishing school I am planning to study communication, so this work experience could be useful for me in future.
I suppose I am suitable for the job, because I am very sociable and good at serving dishes. My parents had a small café so I used to help them. Moreover, I like communicating with people and I never lose my temper.
I will be available for this job in July and August. I would also like to work during a week.
I hope to hear from you soon.
