Dear Sir or Madam
With reference to your adventisement in newpaper, I would like to apply for the job as a shop assistant.
Firstly, I am 19 years old and I have finished upper secondary economic school. I worked in that kind of job in England in the summer in 2008 and 2009 year. My boss was very satisfied of my work so I always got an extra money.
Secondly, I would like to present my two biggest advantages. I am good at dealing with people, so I should not have any problems with customers. And I am keen on math, so I will not make any mistakes with money.
I speak English very well. I lived in England by some months where I worked and I had to speak this language all the time.
I hope you will take my application. I look forward to hearing from you.
