unit3 review, second round

suppose 3~4 kind of situations asking a request with different formality

1. My professor had to attend a seminar and present something, 

but he didn't want to. 

so he called me and asked,

"Can you present the thing instead of me? 

it will be fun, and will be a good chance for you to get experience of talking in public"

2. at the lunch time, I went a Chinese restaurant with my co-workers. 

I ordered 짬뽕밥, but the waitress missed my order. 

So there was no food for me when the others got their ones.

Waitress apologized and promised to bring my food ASAP,

but my co-workers already finished their dishes. before I got my one.

So I asked to the waitress,

"Would you cancel my order?

 I don't want to start eating when everybody already has finished their food."

SO I SKIPPED MY LUNCH.

3. One of my friend have to move on Saturday. 

He doesn't have much stuff, so he think if some of his friend help him, 

he will be able to move without calling a delivery service.

He asked me, "May I ask you to help me to move on Saturday? I'll buy you beer"

But I refused it flatly without thinking.
