Speak in English

In Sanday, I had a part time job at 10:00 to 17:00. Sometimes the visitors of the foreigner comes our cafe. That day, maybe chinese cames to our cafe. They couldn't speak Japanese and also they couldn't understand Japanese but they could speak English. I could understand their order and the woman said to me
"Could you give me a milk?"
I said
"Milk?"
"Yes."
"OK! Here you are."
and I handed a milk to her. She said "Thank you"
I was glad I could do conversation with her in English.
Then, next Japanese costomer ask me
"Can you speak English? You are great!"
I was very very glad heard it. I didn't think I was said like that.
Then, I would like to speak foreigner in English more so I thought study English very hard.
 I try to speak in English if foreigner comes to our cafe from now on. (142 words)
