8 .
You have left something at a shop, to be worked on for a day or two (e.g. printing your photographs, or dry-cleaning a piece of clothing); and when you come back, the work has not been done or finished. You are due to travel home to your own country in two more days' time. What do you say to the shop assistant?
You said you would do this work in 48 hours, but it's not ready: that's disgraceful, and I want my money back straight away.
Well, clearly that's disappointing, and in fact rather inconvenient. Is there any chance, still, that you could finish it for me by tomorrow afternoon?
This isn't good enough, and I want to speak to your Manager at once.
In my country, people always keep their promises.
