SUBJECT: Mary Host_Ichidori Coffee Bed
Dear Manager,
I’m writing in response to your advertisement posted on facebook. My name is Ngan. Currently, I’m sophomore at Nguyen Tat Thanh university, majoring in general medicine. I would like to apply for the position of barista at Ichidori Coffee Bed even though this isn’t my major, but I’m sure with experience learning and finding about barista, I can take this position.

Two years ago, I was a waiter at PopEyes, but for the personal reasons, I had gone to work as a cashier at Highlands Coffee, and that was also my opportunity to learn about barista. Of course, balancing study anđ work has been difficult for students, especially with the health sector. It took me a long time to get everything into the budget which balance study and work as well as entertainment needs. Outside of my own major, I’m very interested in bartending, that’s why I studying barista and came to Ichidori Coffee, because it is a barista’s paradise, which can elevate my passion with a lot of aspects, I also found about Ichidori’s working environment, it is very healthy and friendly.

It's not just an empty promise, I promise that if I ssuccessfully apply for Ichidori’s barista position, I wil work with all my enthusiasm and bring drinks that customers love. I’m eager to talk about the contribution I could make to your firm.

Sincerely,
Mary.

Mọi người cho em hỏi với ạ. Em có câu: "Public transport produces less exhaust fumes than personal vehicles."

Sau khi tra cứu thì em thấy câu này phải dùng "fewer" mới đúng. Tuy nhiên, trong văn nói, có phải là "less" cũng được chấp nhận không ạ?
