[originaltext]M: Hi, I come to pick up my laundry. I brought it here a week ago

M: Hi, I come to pick up my laundry. I brought it here a week ago.
W: Wait for a moment, sir. OK, here you are. We’ve ironed them for you already. Please check and see if there is any damage.
M: I’m afraid that a button is missing.
W: I’m terribly sorry. You know we are so busy today and we forget to sew the button back on. Please wait a moment. It will be ready soon.
M: OK, please.
W: Would you like to have a look? Is it to your satisfaction?
M: Well, oh my God, there is another problem, I’m afraid. There is still a stain on the shirt.
W: It doesn’t seem like that. Sorry, sir. We’ve tried everything, but we’re not able to get it off the shirt. It was from the sugar I think.
M: It’s been several days now, I am not sure.
W: Yes, the sugar was burnt during the dry-cleaning process. And there you go.
M: Oh, that’s so bad. I know little about that. Is there a remedy for it?
W: I am awfully sorry. Please tell us about the stains before the dry-cleaning next time.
M: OK, I will.
W: This is a membership card. You can get a 20 percent discount next time.
M: Thanks a lot.
W: Hope to see you again. We will provide the best service.
